1. Swapped ISP in USA, went from 140ms latency to 2000+ms, help

    I had standard cable line here on the east coast of the USA, usual latency is around 140ms for the past 4-5 months I been on Warmane. No serious lag or latency issues outside of general server issues.

    I switched companies to a fiber line with AT&T, now...I can hardly ever get a standard 140ms latency delay. Normal to this is around 300-400 with just standing around anywhere, and when I get in an ICC25 or 10, it spikes to 2000, 3000, 6000, even a 7000ms delay. Outrageous. Not a single day since I swapped providers from almost 2 weeks now has been a normal experience.

    Friends that has had AT&T that live an hour away that play this has raved on how they havnt seen lag, had less than 100ms latency, and have had the service for 3 years and played about the time I started. Well, my bill got too high with cable and decided to get on their platform. Now, they have started to have problems as well. Starting around a Warmane update around March 2nd, all 3 of us are having simultaneous lag issues. Something around that time, or in that update, has started to mess with something and the routing from the USA to the server. Has anyone found a fix (other than a VPN or switching back to cable) that can help with this continuous lag all month long? We are all Donators, and just want to enjoy the game again as this is becoming an issue.

    Just to make sure nothing is on my computers end, I held on to my cable service to "make sure I liked fiber", and the lag issue was not with cable. Just AT&T Fiber in my situation. So other fiber companies may have trouble as well? Not sure.

    Things I have tried.
    Port openings for Wow
    Leatrix installed and uninstalled
    Configuring router settings

  2. I've been having the same issue with ATT FIber as well but my friend has ATT non-fiber and gets the issue too. Issue has been going since Jan for us. Saw a bunch of other ATT customers saying the same as well but ATT is saying its not their issue. VPN solves the issue for us too but its bs having to use one to play. If enough people posted maybe we could use it as evidence of an issue?

  3. well, the 3 people in my guild that have issues with connection all have ATT here. Not sure if warmane can get better routing for ATT users to connect to their server more smoothly or what, but this has been pretty insane since i swapped. I do NOT want to go back to comcast, as all my other games/streaming has been so much smoother for local internet uses. so i am a happy customer, but, not happy that it has trouble connecting to warmane initially :(

    we did get a day or 2 of ok connection, but really noticed a quite amount of lag to make it almost unplayable on some boss fights in ICC. as a rogue, i am always too far away to hit the boss when they are moving. hurts...

    This is out of Warmane's hands because based on my analysis it's a specific application traffic signature AT&T is targeting and throttling. I've checked traffic from multiple residential AT&T connections with different routes across the US. Covering traffic via a VPN resolves the issue. I've made sure to get my VPN machines in DC's between hops.

    Here is one example, tables modified to make it easier to digest.

    AT&T doesn't seem to care about throttling VPNs (yet?). I've tested both OpenVPN and GRE/IPSec. I've not bothered to test a plain unencrypted GRE tunnel to see how much effort they're putting into this.

    It's possible this is actually an accident, but I'm not sure with NN being dead.
