Spiky Latency

I've been getting some weird latency problem lately. While playing, I get latency spikes of up to about 2s (sometimes less). If I look at the graph, I can see the spikes corresponding to when I can feel it (spells not casting, etc).

If I'm just standing around in my hideout, this doesn't happen. But if I start moving stuff around in my stash or actually playing the game, I get spikes. Please check out http://imgur.com/a/jSbbj - I took some demonstrative screenshots.

I've pasted a WinMTR log below. It seems like hop 3 out of my house (32.210.40.2) may be the culprit. I'm on ATT Uverse on the east coast USA.

I tried setting up some QoS on my router (runs Tomato), but that didn't seem to do anything. I'm not experienced with QoS so I may not have configured it in a useful way. I did it on destination ports 12995, 20481, 6112.

Any ideas? It has been going on for a couple weeks now.

this is exactly what i'm going through
Update: I was on the phone with tech support at ATT last night and surprisingly the guy was very informed and helpful. He didn't immediately tell me to get lost when I told him I was running a router with Tomato.

He couldn't find any problem on their end and he has no idea why my external IP is located in AZ while I'm in CT. He recommended I changed back to their DNS servers from Google's and I did so, but that didn't change anything (no idea why it would).

Still experiencing the same problems with PoE though.

I'm not sure where he got the idea that your IP is in Arizona. You're clearly routing through NY which you likely wouldn't do if you had an Arizona IP address.

Since not all the hops resolved properly, I cannot tell you for certain... but you can go to http://www.geoiptool.com/ and get your IP Address and the assigned "geolocation". Also look through a successful trace at the "location" of each hop... it should match what you have.

Although that ISP tech might have been more helpful that otherwise, it doesn't sound to me like they still knew what was going on completely.... Arizona?
Well, whatismyip.com says Phoenix, geoiptool.com says Kansas. Either way, not CT or NY. But you're right, I do see the ny stuff in the trace.

The only hop that worked in geoiptool was ae-15.r05.nycmny01.us.bb.gin.ntt.net, and it came up with Englewood, CO.
sounds like someone never updated the locations on the addresses they purchased.

very strange but not uncommon. the DNS names are usually right.


There's a pingplotter output - looks about the same as WinMTR.
