Network has been much nicer this week. Keeping fingers crossed.

I just wanted to post an updated. It appears things are getting better with Comcast's network. Unsure if the good times will continue but I'm crossing my fingers...

Re: [Connectivity] Major Slow Down in San Jose, CA?

i'm in garland texas(the dallas area) and comcast has been very slow for the past week at least. comcast.net loads so slowly my former dialup ip could do as well..also trying to open dallasnews.com to read the paper?? i might as well subscribe to the daily paper..it would be less aggrivating than waiting for their site to load. it's really annoying to me cuz i gave up netzero 3 weeks ago for comcast high speed..and now this cr&pola..this had better get better or i'll be saying goodbye to comcast.
it seems like the pages that load the slowest are pages that contain graphics,which i could understand if i was using dialup. i certainly didn't expect comcast to be a problem in that area.

SBC takeover of ATT shouldn't have anything to do with this. Comcast already tookover ATT's broadband infrastructure awhile ago. Comcast tried feeding the upgrade to Northern California but recalled it immediately (I saw my modem's config). Why? They can't handle it. Yes, I may be ignorant, but I can still speculate!
It won't have anything to do with the immediate problem. Like you, I was speculating. AFAIK, the AT&T core routers were not a part of the AT&T Broadband Internet infrastructure, and remain under AT&T control.

To continue to speculate, though, maybe a regulatory restriction will be placed on the SBC buyout; the AT&T core routers would add to SBC's significant place as a backbone provider. Maybe the routers will be required to be sold off to Comcast, who would then have tighter control over them. This should be a "good thing" for Comcast, as it would give them their own backbone, as well as giving their engineers the ability to tweak the routers for improved performance.

OTOH, if they stay with SBC, then any performance improvements would be on the SBC network engineers. Perhaps tweaking their performance would have a lower priority; as long as the packets actually reach their destination, why expend effort to reduce lag for a competitor?

I am sure the majority of Comcast's users base uses their connections in the evenings since the majority of the people out there do have jobs. Your welcome to post your speed results but I would prefer you send your latency results via a traceroute or ping to major websites (google, yahoo, etc) at 8:40PM. If your not in California then don't bother.

Ok, is now a good time?
Any other sites you would like traced?

Speed tests will likely piss off a few people, tracerts will depress many.

Remind me this evening at the time of your choosing, I'll be more than happy to provide the above stats.

The problem is the second hop. My second hop has been down for several weeks now.
Do you mean the hop that fails? Like everybody else's trace routes show? I am told that it's your CMTS, and that is is configured to not respond to ICMP packets; no ping.

That is looking into a Comcast user's IP address. Their CMTS doesn't respond from the outside, either.

I noticed quite a few are posting tracer routes going through Level3. I'd kind of take those with a grain of salt, given the peering wars going on.

I also wonder what will go on with the AT&T routers. With SBC poised to buy AT&T, how long will any peering and transit agreements hold?

Comcast may be adding capacity to take up any slack from the AT&T buyout; who knows? I also have no idea about the affect of Comcast lighting up large swaths of the south S.F. Bay Area. Until about nine months ago, Comcast was not available in my neighborhood. That was when they "lit up" the line behind my house. Black sheath with red stripe; fiber on the poles? Could they have added customers in west San José faster than they added capacity, and are now playing "catch up"?

Just rambling. I was suffering serious DSL lag, and decreased down sync rate; worried that the copper was going bad, and I'd maybe have to go over to Comcast. Now that the cable maintenance guy fixed the open on the "ring" side of the loop, all is well again. Took them 48 hours to fix it, though, because of the "protocol". Service techs have to wave their wands over pole connections and cross-connect boxes before they bring in cable maintenance.

This is clearly an issue with their overall avaliable bandwidth leaving their network. My thought is marketing keeps increasing the avaliable bandwidth to each individual user but Comcast's network cannot handle it and thus it falls over during peak times. This *must be* a known issue within Comcast's network team. However the technical support technicians are probably either informed not to say anything or are unaware of the problem.

I do understand how long it takes to get new services ordered through AT&T so therefore I do not falt them on this one. However I have seen this problem for 2 - 3 weeks now and it will either get resolved next week or Comcast is stringing their customers along.
By "their network" do you mean all of Comcast?
Would you consider 8:37 PM "Peak Time"?
I won't post a speed test unless I am asked, but I can assure you my speeds are fine here on Comcast.

I am having this problem a little east of you guys in Davis. I talked to an engineer and they told me that they are aware of the problem. I called up Comcast today and told them I want a credit on my account for this month. They put it through. Money talks, tell them you are not going to pay for a service that does not exist.

Yah i really fear that this problem will never be solved because comcast is just too big and cannot handle individual problems anymore.

I'm ordering DSL and testing it for a month to see if it's better because i really dont even know how to approach the comcast issue.

Are there ANY comcast techs that browse these forums who can give us advice here???

reply to blacey
haha most of u people have what max of 3-4 weeks with these unbearable speeds from comcast?....listen to this 4 fuckin months wow i call comcast have 4 techs within 3 weeks and 1 of them says i can't find anything i'll give u another modem...doesnt solve the problem, the second one says i can't find anything wrong you want a modem change and i told them to give me their motorola sb5120 and still nothing 3rd tech tells me that it has something to do with my apt cable lines...and im liek fuck it let them say what they want to but i ask him tho how is it possible that when i call comcast customer support they tell me that they see the ping times on my modem and have proof yet when techs come they say they cannot go any further or else they will have to do a surcharge of 49.99 because they have no proof and tell me that comcast techs and comcast customer service are two different parts of the company...only word that comes to mind is WOW. so i was thinking recently how could i have such a retard to listen to that bullshit if a cable line was bad in the apt why do i get great ping in the morning while im in class so i call them back for a escalate in my problem from a regular tech to a line tech who tests the line instead of my equipment. now some lady from comcast calls me while im in class and leaves a voicemail saying they didnt send a line tech because it is a problem that has to do with where i live and the cable lines in my apt. btw i live on 4th and william area code 95112.

WAN Traffic

Ping latency to Comcast.net
This is what I have experienced in Foster City. Notice that my WAN traffic is low but the last three nights, pings to comcast.net spike between 8:00 PM and Midnight.
