Problem with traffic to Blizzard servers (World of Warcraft) via Cogentco

same exact issues here, had the same problem a couple months ago and it stayed this way for at least 2 weeks, hopefully this gets fixed alot quicker this time because it is pretty annoying

seems like the latency gets worse and worse every day, my ping in blizzard games has gone up by a consistent 40 every day since saturday, please fix this

I've also been experiencing this, I've made a support ticket with Blizzard hoping they can some how help resolve this issue, although the problem lies with Cox and AT&T, the issue is especially frustrating given that i've recently forked over money to blizzard to transfer my characters from a Dallas server group, to an LA one, only for me to be routed right back to Dallas then to LA.

I too have been noticing this issue for the past week or so. Hope this gets fixed soon.

From the data in the thread mentioned, it looks like a peering issue. Last time Cognito fixed it, but took a week or two. It is outside Cox's network. Have you tried calling Cognito?

I have the same issues, and I am getting really sick and tired of it.  I am freezing up during combat in dungeons, scenerios, and LFRs. All of those are pretty much unplayable. I sent this to Cox email support and they didn't read what I wrote and just stated to power cycle the modem.  Cox techs have been to my house twice, and I purchased a new modem and wireless network adapter.  I have the same problem when I play wired, so it is not the router.  I have this issue with a fresh install of WoW with no addons.  PingPlotter shows packet loss over numerous hops along the route to the WoW server.  As you can see below, there are also issues going to the google server.  I have been having this terrible latency and packet loss since February 2013!

I'm noticing the issue...have been for several months.

I noticed it got better for a day or two last week or so but then it went back to the way it was and today was in particular brutal. I got frequent lag spikes up into the 300'ish ms range. Usually when I'm lagging it hovers at about 150'ish ms.
