Re: Who needs those classic things

Those are comm links in the event of a catastrophic failure. Those are not used to route data or voice at the moment and won't be unless they are absolute last choice.

You have been watching to much tv. Data and voice over satellite is very expensive. And there is not data routed over a satellite link for any backbone needs at all. No one is stupid enough to do that.

Nasa does not launch the satellites I'd hate to tell you that. A separate company does. And they ship the satellites out to the equator to launch them from a boat or even from places in Europe and china. Nasa releases government only satellites.

As of this writing you can still view their fiber hops that are lit. Even level3 lets you view them.

The internet backbone, most of it, has very little to do with sattelites anymore. Most of it is fiber, ever under ocean fiber cables.

Your speeds you talk about and services that actually benefit from sattelite is one way. That is because the delay it takes to get to you really does not matter much because it is a steady data stream, like a TV broadcast.

Fiber is limited only by electronics so your OC-48 (2.488Gbps) or higher far beats your Sat speeds with about 300 times less latency.
No, the cool thing about the internet is it was built to have multi routes it is Sat. and Fiber based. Right now all of the long distance companies are hiding the fiber routes and working on their sat contracts. It makes since to route fiber to Europe, Japan, and Asia but the cost per mile is still in line with having a bird in the sky. Also, when the internet went into the public domain it was kicked off of the sat net that the new internet that the research universities and companies are working on. They have both dark fiber and dark sat. channel routes to connect the world to it.

Right now there is a back log of birds to go up because of NASA, EAS problems with payload delivery. So right now fiber is holding its own.

The public at one time could see on the web the fiber routes and pictures of the IXC CO but because of concerns of terror attacks MCI, AT&T, Global Crossings and others are working to get more birds in the sky in addition to the fiber and coax.

Good clarification -- I was waiting for someone to jump down audiog's throat.

If the internet "backbone" was over satellite, you'd never get better than 800ms on a long haul ping.
