Yep, the latency starts after Comcast handed the traffic to ATT.
W.I.W., it appears that CC handed the traffic to Tata/Teleglobe, which then handed the traffic to AT&T.
Funny you call me on that, it was even said before I made that post. So yea....]]> http://www.dslreports.com/forum/remark,22599800 Tue, 23 Jun 2009 20:52:31 EDT Re: High Latency and online Chat's refusal to acknowledge a prob http://www.dslreports.com/forum/remark,22599176 EG :

No matter the problem, it's Comcast's fault.
It's their use of Sandvine! :D

(For those who take things too literally, that is supposed to be hyperbolic humor, not truth. Based on the controversy over Comcast's former use of Sandvine to throttle BT.)

Imagine that.

AT&T went from having Comcast's not-insubstantial traffic entering their network from a couple of routers per Comcast market (several hundred routers in total?) to receiving it from a limited number of peering points where they already had a lot of traffic coming in from peers like L3 and Tata. Sort of like switching a showerhead from normal to massage mode. :)]]> http://www.dslreports.com/forum/remark,22595795 Tue, 23 Jun 2009 09:49:32 EDT Re: High Latency and online Chat's refusal to acknowledge a prob http://www.dslreports.com/forum/remark,22595509 anon : Yep, the latency starts after Comcast handed the traffic to ATT. Comcast is not an ATT customer per se here, whoever is hosting the server is an ATT customer. The fault lies with ATT and their customer. It's up to their customer to get it resolved.

I seem to remember there were problems between AT&T and several other ISPs including Sprint and Verizon. Blizzard pays AT&T to be their ISP and they need to fix it with them or diversify their connectivity.
Agreed ! Single homing for them = ridiculous !!

Just pointing out that the issue is between those two interconnect points in that particular trace.]]> http://www.dslreports.com/forum/remark,22594076 Mon, 22 Jun 2009 22:13:15 EDT Re: High Latency and online Chat's refusal to acknowledge a prob http://www.dslreports.com/forum/remark,22593954 yt :

Actually Comcast aknowledged a routing issue on their end a couple of days ago (on their forums). They did some re-routing to the WoW servers. Im thinking this is the same issue.
I doubt it. Given Blizzard only has 1 ISP and the WoW forums are showing problems with many different ISPs (not just Comcast), I think the fix is really Blizzard's to address. The first thing a network engineer does is multi-home vs. putting all your gaming eggs in one (not so great) basket. I would think a gaming company that has millions of online customers would use more than 1 ISP. How do you route around issues if you only have AT&T?

That said, you should try a realm closer to you... say Dallas.

Everything on comcasts network and their initial link to ATT is fine. This is an ATT issue inside their own network.

Time to contact blizzard and have them work on it.

The problem looks to be with ATT. Not something comcast can really fix. Everything on Comcasts ibone and such are fine.
QFT - This looks like an issue that your Game provider should address with their ISP. Hopefully they have more than 1 ISP and can route around AT&T isssues (which appear to be growing)

You may also try and use a Game server closer to you.]]> http://www.dslreports.com/forum/remark,22593791 Mon, 22 Jun 2009 21:18:59 EDT Re: High Latency and online Chat's refusal to acknowledge a prob http://www.dslreports.com/forum/remark,22593769 beachintech : The problem looks to be with ATT.

Your hop 9, 192.205.35.57, is an ATT edge router, which has a good link with comcast.
