Problems again with SR :(

[Prof.Wizard]

Today 1st February, the site has been extremely slow... :(
Did anybody notice? From Europe it was almost unaccessible. :cry:

[Tea]

I was on at much the same time, Prof. It was working OK for me. But quite often I have problems. I suspect that SR's server belongs to an interconnected chain of some kind that a lot of places share. (Don't know the fancy terms for this stuff - help me out James?) I say this because often when SR goes into mega-slow mode, a number of other US-based sites do the same. But not all. It's almost as if the US is hooked up to two or three enormous backbones and from time to time one or other of them gets a case of gridlock.

But yesterday must have been a trans-atlantic issue, I think. At least if SR was down, I didn't notice it, and I flicked in several times through the day.

US traffic congestion usually comes from public peering points like MAE East (where most European ISPs meet the US ones).

If you (or your hosting provider) buy your connectivity from the only two companies with a real global IP network - Worldcom and Cable & Wireless - then service should be better because both have an enormous number of self-provisioned private peering points, which are much more reliable (and less congested) than the public ones.

However, the network managers need to be competant and get rid of traffic destined for other networks as soon as possible.

Apparently Telstra doesn't peer properly with Worldcom, for example. Burst.Net gets its connectivity from Worldcom, and Telstra has an interconnect with Worldcom here in Australia. However, Telstra seems to prefer to carry the traffic to the US before giving it to them (BTW, those interested in the cable discussion in "Big Pong" thread can see from the traceroute below that Telstra has abandoned Southern Cross in favour of the new AJC cable and HKT's capacity on TPC5 via a cable switch in Guam) :

Ouch! Compared to here, that tracert has some high pings

How is the site running now?

[James]

Well, I am 11,000km away. That's pretty standard for connections to the US, although on Optus it would be about 70ms quicker because they use Southern Cross.

In today's lesson, kids, we learn why it's a bad idea to use AT&T as your IP carrier.

The tracert to SR goes much the same until here :

I'm out at Belinda's amongst the gum trees right now - a poor line, but what do you guys make of this?
