Level 3 Cogent Cutoff Problems Continue
(old news - 10:48AM Thursday Oct 06 2005)
As we were the first web outlet to mention yesterday, Level 3 terminated its peering relationship with Cogent, leaving many user unable to hit a number of major websites since early yesterday morning. Discussion Continues on NANOG, where many continue to place blame at the feet of Cogent, for taking advantage of lopsided peering arrangements. Slashdot, the Register, and CNET have since covered the story.

Cogent CEO Dave Schaeffer is apparently weighing every option except actually paying Level3 for the extra bandwidth, stating his goal "is to have this problem go away, whether through Level 3 reconsidering or their customers coming to us." Translation: affected customers will be waiting a while.

Re: "BS"

Actually not BS. I used to do peering coordination and believe me some companies just think they don't stink. I remember sprint requesting we PAY then nearly 100k per month per fast ethernet peer we had with them (4 at the time.) Yet my contacts at MCI/UUNet said they did not have to pay anything.

This is likely the case with Level 3 not liking its peering arrangement with these more broadband centric companies expecting cogent and RR to pay the meatier portion of the deal. The thing is, if level 3 plays that game they will just loose customers since hosting providers need to get to the masses and that's it.

Additionally, even if peering was cut off usually you would get another path, so it sounds like to me that either peering contracts have changed and you get only that peers routes, or level 3 is intentionally black holing routes.

But that's all pure speculation from years of running ISP backbones.

That's actually what bothers me...
If Cogent was only peered with L3, then noone could access them. That some people can mean they have multiple peerings.

So if noone whose main access is L3 can access Cogent, it means that the packets are still delivered by L3 to the dead peering, instead of letting the routing process decide where to send it... Either that, or they erase all Cogent routes everywhere on the backbone... In any case, sounds really hardcore to me...

You forget that Level3 is really a Tier 1 ISP. By definition, if the links to Cogent are down, there are no routes to Cogent. Simple as that.

If Level3 wanted to reach Cogent in some other way, they would be paying one of their other peers to carry traffic to Cogent, which would mean two things:

-They are no longer technically a Tier 1 since they are paying for transit to some other network
-They are shoveling out money to reach Cogent, which would be the opposite of what they want to do

The quote from Leo on NANOG sums it up rather well:
As for those who want to re-architect the Internet to "fix" this
problem, please go away. It's not a technical problem. It's a
business problem. Two companies, each responsible for their own
bottom line couldn't find an economically feesable way to interconnect.
Any attempt to "force" the interconnection (either via regulation,
transit through third parties, etc) will RAISE prices for all
involved. The key here is that the peering was not economically
viable for some reason.

If Cogent was peered to no other Tier 1, yes... But since they are (which seems to be the case as other people can still reach them with no problems), I don't see why the whole level3 AS is a black hole regarding Cogent routes....

I do understand your point about the problems were L3 to send packets to UUNet for UUNet to then forward them to Cogent. However, I don't see how else it could be done. L3 is not peered with every single AS on the planet, are they? Meaning they must be delivering some traffic to other tier 1s to reach some destinations.

I must be missing something to understand this, but I can't figure out what...

You are missing something...the concept of peering. Peering relationships involve only trading your own routes and your customer's routes and your customer's customer's routes. Peering relationships do not provide full internet routes between peers.

I get that. What I don't get is that
1) if Cogent is no longer a peer of L3
2) if Cogent is still a peer with (let's say) UUNET (or another Tier1)

Shouldn't Cogent now be considered by L3 as a customer of UUNET and therefore be accepted inbound on the UUNET L3 peering? Or is it something that's not automatic, and Cogent didn't do that?

No, Cogent is not a customer of UUNet. That's the whole point of peering. While Cogent does pay at least one Tier 1 for transit, they only pay that Tier 1 for their routes and their customer's routes. That's the whole point of peering - you trade only certain routes - not a full routing table. A true Tier 1 in the traditional sense of the term, does not pay *anyone* for bandwidth or peering. They only invest in themselves for the upkeep, equipment, and maintenance of the peering session(s).

For example, If MCI/UUNEt one day decides that Sprint is no longer providing a mutually beneficial peering arrangement (Sprint sending more traffic to UUNet than UUNet is sending back), and UUNet de-peers Sprint, then UUNet and Sprint networks will not reach each other. It has nothing to do with access lists or access filters. It's how the internet and the underlying BGP protocol work. Sprint would then be left to either re-negotiate their ASSES off with UUNet, or be forced to purchase transit from UUNet or another Tier 1.

This has happened before with large providers and will continue to happen every once in a while. It's unfortunate that the smaller fish is almost always the one who will pay dearly in the end, but that's how life (and the internet) is. It's full of uncertainty and unfairness.

It is called the TRO the FCC ruled in March of ordered that the Unbundled Network Elements in Co's with more then 50% fiber will no longer be tied to a cost base report done on an annual review by the Regional Bells who own the majority of the CO space in the US. This means Bellsouth, Verizon, SBC and Qwest can charge a market or commercial rate that is not that much lower than what a reseller pays. All of the big deals that Level3 has done in the last few months are with guys that are resellers ( Vonage, 8X8, Earthlink; Comcast and Adelphia are users of the Regional Bells UNE-Platform that is going away in March 2006). With the network recon-figs and the reroutes that are happening due to down fiber in the south this is a sucky time.

Cogent is now looking for a new partner while Level3 is becoming a VoIP carrier carrier and giving them a high QoS. With short hops from the internet into a VoIP gateway with a global network.
This is the World that the FCC wants.

Now you know why AT&T and MCI looked so good to SBC and Verizon. Forget UUNET its the global Fiber bandwidth at the number 1 and 2 long-distance carriers have. VoIP, Video, music and more with a house past network that none of the cable guys or the Direct TVs of the world can match. Now can they make it work?????

@qwest.net

It's not the case that L3 is dropping the packets. Think about it. If Cogent was truely a Tier 1 ISP, they would have multiple peering connection as does L3. L3 has over 300 Gigs of peering connections. If they close down thier Cogent connection, and an L3 router gets a request for a cogent route, they send it to one of thier other peers, and it would in-turn deliver to cogent. That only works if 1 - Cogent has peering agreements with others and 2 Cogent doesn't black-hole a packet with an L3 header. Since cogent has other perring agreements, then Cogent must be dropping every single packet it sees from L3. It is the ONLY explaination...Right? I asked some friends with cogent service to trace route a ping they made to L3 web site. It died. I asked them to ping MCI web site, low and behold it went right through. My company uses L3, so i asked the guys to do the sames test, the trace route said that the request to Cogent's web site was routed via a UUnet router, then it died.

It as simple as that...Cogent, with 60 days notice from L3 that they were going to de-peer them, did nothing to prepare the event, instead made a political power play and is blaming L3.

Do some research before you post. Cogent peers with more networks than some of the largest Tier 1 providers.

Wrong again. There are *multiple* L3/Cogent peering points. You obviously don't understand how the internet works. If L3 shuts down their Cogent peering sessionS, then they cannot reach Cogent and vice versa because there is NO ROUTE to the Cogent network. Peers do not announce other peers' networks to each other. That would be called TRANSIT, not PEERING. Read up on BGP and the concept of AS-paths before you spread misinformation like you know what you're talking about.

Blackholed...

Thats exactly what Level3 did.

Normally if the links between Level3 & Cogent went down, traffic would just flow through one of the other Tier1 providers - Sprint, UUnet, etc. Thats the whole beauty of the 'net!

But Level3 is actually blocking traffic by removing the BGP routes on its routers to all of Cogent!

If a Level3 customer tries send a packet to a Cogent site the routers respond with no route to host.

If a Cogent customer tries to send a packet to a Level3 customer, its actually still getting there through alternate routes via other Tier-1 ISPs, but with no way to respond it doesn't work.

False. The way it works is that Level3 routers receive the Cogent routes either from Cogent over peering links or from other providers that cogent uses as transit. If Level3 doesn't receive the routes one way or the other then they don't have a path to Cogent. The peering links were turned off with multiple weeks' notice and Cogent did not make the arrangements for Level3 to get the routes through one of their transit providers. Cogent could have sent the routes as well as received the level3 routes through someone like Verio.

WHAT?? L3 should pay millions of dollars a year to maintain peering conenctions that provide them no value?? peering only works if something is mutually benefitial. Routers, cards and data center space, power and cooling isn't free.

Simple test - an equitable agreement would be what?? your inlaws could stay with you for two weeks a year, in exchange, you get to use thier beach front Hawaii house for two weeks a year. Instead, they stay with you for 40 weeks a year, and you get thier house for 12 hours per year? is that equitable? You get to pay for the increased food, water, gas and electric bill.

Nope. Here in Denver they were totally reliant on Level 3's network. Yesterday while trying to reach Cogent network resources, the Level 3 routers would just drop the request. Last night, Earthlink rerouted all requests for Cogent network addresses through WCG.NET routers to get to the Cogent network.

How sad that a major consumer ISP is single-homed. I do work at a much smaller shop (ie: one PoP in NYC), and they are multi-homed. If nothing else, it lets us seemlessly ride through Level3's maintenance windows. And now it's allowing us to reach Cogent via our secondary provider. Not a single blip for their customers, which is as it should be in this day and age.

EarthLink is multihomed. They peer with other carriers at major POPs, and they run BGP on the internet facing routers. What I meant to say is that they don't have their own fiber anywhere in the ground. In fact, other than the telcos, there are not that many companies (and even fewer municipalities) that do.

Interesting Comment I read on another board...

I do not wknow who wrote this but I saw it on another board. I thought it was interesting.

(snip)

The thing is that Level3 *isn't* being an asshole. They were giving Cogent free connectivity to their network. At some point, level3 decided that the peering agreement was one-sided and Cogent was getting more out of the free connectivity than Level3 was so they asked Cogent to pay for it. Cogent refused. Level3 cut off the free connectivity. There are lots of reasons why this will work out better for Level3 than for Cogent.

First of all, Cogent's network sucks and always has so just about every content provider on Cogent also has a backup provider. This means that even if Level3 cuts off Cogent, Level3 can still reach Cogent's customers via the backup (multihomed) path. It just means that the traffic to level3 takes the backup path.

Secondly, Cogent has almost no end-user eyeballs on their net, they are mostly high bandwidth (porn) providers. In other words, most of the traffic flows OUT of Cogent's network and very little flows in. When you make a peering agreement with someone it is generally done to the mutual benefit of both parties. In this case, the peering was to Cogent's benefit but level3 probably didn't have a lot of traffic headed towards Cogent so the agreement was really one sided. What eyeballs Cogent has is for their leased dialup service which competes directly with Level3's leased dialup service.

Thirdly, Cogent undercuts everyone's pricing. Why should Level3 give free connectivity to someone who is taking business away from them and whose network isn't a major destination for their traffic, and whose customers it can reach anyway over an alternative path?

Bottom line ... Cogent is a tick on the ass of the Internet and unless they clean up their act and actually make it worthwhile to peer with them, other providers are likely to follow Level3's lead.

Single homed customers only. Multi-homed customers will have routes via other providers. People are saying that Level3 was missing about 1000 routes and Cogent about 4000 out of the overall 150k on the Internet today.

Should not (being the objectionate word) be affected by this. I had a discussion with one of the backbone guys yesterday. We are a peer to level 3 however if it tries to go to congent networks it may die on that end.

SBC is a peer of it's own so according to who I have been talking to it should have little impact on our operations.

Re: SBC customers

Well the present SBC customers I was advised should be unaffected, unless you attempt to possibly hit a cogent site via level 3. However from what I gathered yesterday that should not be the case based on the peering agreements between level 3 and us. You still might have the connection problems to cogent hosted sites. That is the unknown, I was mainly advised it should not affect SBC customers greatly or should be minimal impact.

Here is part of the conversation I had with one person that works on the backside of things. Names removed to protect the innocent.

linked to article for reference for "peerin fool"
»Level 3 Peering Changes Causing Headaches

Beach boy(17:46:38): I suspect seeing pages on cogent networks might be kind of hard to do and other customers trying to vpn to other locations might cause our traffic to increase.

Beach boy(17:46:52): please advise when you have a free minute, and thanks ahead of time..

peerin fool(17:51:00): this sounds like a problem where customers of Cogent's network will not be directly handed off to Level3. We peer directly to Level3 ourselves, so no outgoing problems there....now as far as how we get to Cogent's network, that's anybody's guess depending on the links, routes, and costs of the links

Beach boy(17:52:13): So technically if a webpage is on cogent's network a SBC user might not be able to see it... depending on costs of the links.

peerin fool(17:52:58): they should be able to get there....just not via Level3 - Cogent should have multilple peers as we do

Dumb question but i have to ask

Is level 3 Goverment control or is it just a company that routes to web sites?

No, they aren't government controlled. They are a publicly traded (Nasdaq: LVLT) company. Their corporate HQ is right down the street from me.

Boycott

That's it I'm sick and tired of all this.. I think we need to email everyone and not use the Internet this Friday. Maybe if we all get together we can make a statement.

Please enlighten me...

what are the implications of this regarding email routing? Will it bounce (and I will then know it didn't go through) or it will just disappear and I will never know about it?

Re: Please enlighten me...

When you goto send your email to domain.com, domain.com will no longer exist because the DNS entries are dropping off.

Your mail will be bounced back. Unable to send.

RR the only ISP effected by this?

I was doing some testing, and noticed that I could not get to a friend's rr.com internet address from a Cogentco.com connected server I have access to. It timed out right away before it even got to hop 2. This server only has a cogentco connection, so I was able to test and see exactly what the issue was for myself. Most ISP's I know have multiple peers, for example I know Cox San Diego piers with Level 3 and Cogentco directly, so one terminates the other, cox users won't have to worry. Is RR the only ISP that has just one transit peer? This obviously is not RR's fault of course, but I haven't heard of any other ISP having any issues presumably because they're smart and have at least 2 transit peers? By the way if anyone wants me to see if I can get to their IP from the cogentco server, just let me know.

Time Warner is affected. And yesterday my Earthlink DSL couldn't reach Cogent addresses either.

The problem arises when all your traffic that was going over two peers now goes over one peer. If their was a ratio problem, then your remaining peer is going to get ticked off and might want to drop you as a result.

Amen to that

No problems at all in COX San Diego. I see myself going through cogentco routers and Level3 sometimes, but never on the same tracert :P

RR in Los Angeles routing resolved!

At least for me, it just started working again so either someone blinked or they re-routed!

Does anyone know what Drudgereport did?

I can't access a lot of sites, but Drudge Report came back up quick as always today, not not yesterday. Hmm usual I should say instead of always given this, and I think that was one of the ones originally effected.

I was wondering if they changed hosts or the route simply changed, or maybe it wasn't effected but just happened to be down yesterday which isn't a likely coincidence.

Re: Does anyone know what Drudgereport did?

I'm getting Drudge Report through LEVEL3.NET, SVWH.NET, then CENTRALHOST.COM . I had no problem hitting them yesterday. But yesterday Photobucket wouldn't come up, and they are on a Cogent network.

RR in Texas Working

Road Runner in Texas (San Antonio) seems to be working now. Connections look like they're going thru ATDN.NET instead of Level 3 now.

Re: RR in Texas Working

Try doing a trace route on yahoo.com . You should hit Level 3 then.

tampa bay RR working now

RR out of N tampa bay is now working. I have used addr.com for several years and was unable to connect to them the last 2 days. I see that cogent and level3 are still at war, so either addr or RR is making this connection work, and I thank them for that. I was wondering how I can find out which one did the fix, as I will probably dump the others services. After doing a trace to addr.com it looks like they are still using cogent, so they just sat on their ass and waited, while RR probably rerouted the connection? Is this the case, and should I dump addr.com?
