Title: Cogent / Telia peering is messed up (again)
Post by: jezuk1 on Oct 11, 2010, 20:33:58
This was an issue about a month ago, and the problem is back again. World of Warcraft lag is huge (400ms+) and basically unplayable.

Why is this happening again? It's happened before, it's happened again.... What's to say it won't happen in the future. There is obvioulsly a recurring problem here. Can we please have some information about what's going on? When will it be fixed?

It not localised to Idnet though, below is tracert with similar lag from a non Idnet customer.

His end destination has a 44 ms ping, he's not affected.

Sorry I should have looked more closely.

Definitely looks to be Cogent's peering that's buggered, Blizzard's support people will inform us to pester the ISP and have them pester their peer to resolve this.

I can confirm this seems slightly off.

Is it still this high today? I logged in briefly before work this morning and MS was 140, was 500-1200 last night. I was rather hoping it might have been a one night affair.

I don't know about anyone else but since this last latency issue my in-game latency monitor is giving me consistently better results than I've ever had before with IDNet. It's been particularly low for the last 24 hours even in populated areas on highly populated realms. It seems to me something has changed but the routing looks the same.
