Higher latency due to using Oceanic server for instances

It doesn’t happen every time but it does happen more often than not during peak US hours.

Be sure to post your WinMTR and to delete your WTF/Interface/cache folders.

This has happened once or twice in the past. It’s pretty rare, but not unheard of and we can test for it pretty easily even if we can’t reproduce it always on our end.

edited: Removing a test requested earlier. We no longer need server IPs. Thanks for the reports!

Let us know the following for the character having the problem

  • Character Name/Realm
  • What Instance You Were In
  • Time of Day/Timezone it Happened in

That’ll give us more info on when/where we need to test to reproduce things. If y’all can reply back we can give it a peek and try to find out if you’re ending up on the wrong server group for some reason.

No need scare people away by asking them to dive into the command line. Use Microsoft’s TCPView utility which will show everything that is needed.

By default everything will be sorted by program alphabetically. The relevant remote addresses will be the ones on remote port 3724.

On my end connections should be to 24.105.3x.x IP’s in the central US datacenter but they’ve sometimes been connected to 103.4.115.x systems upon zoning into instances.

It’s been happening frequently for several weeks and almost always during normal US peak hours. Example from last night I was placed into an Oceanic instance upon zoning into Throne of Thunder and Dragon Soul.

Edit: I’m rolling through repeated Shadow Labyrinth runs on Duskwood at the moment and everything was fine until just now where I got an instance on 103.4.115.155 and latency went into the dumpster.

In the next two instance resets I was placed on to 24.105.32.254 then 103.4.115.155.

My latency was 18 before entering the raid and like everyone else here and in my raid it spiked to 250ish. It returned to 18 after leaving the raid.

Hello Kaldraydis,

i am having this issue as well with extreme world latency both inside and outside of instances. I am connected through a hard line through google fiber. I have a strong connection to not only state further facts.

I walked in exactly at 10 CST and immediately my world ms doubled my home ms. After staying in the raid for 5m my world ms jumped all the way to 250+ where home is still sub 20ms.

My whole server and a bucn of friends from USA have also been experiencing this issue for the past 2 weeks. There is a 1 second delay maybe caused be packet loss and high MS.

This happened for our entire raid tonight also. The only person with playable world latency was a raider who was playing from Australia. His ping was 55, everyone else’s was 200+.

We called the raid due to the latency limitations otherwise I’d post the requested stats.

blizzard’s official stance on this isnt you guys going to pretend like this isnt a real thing that is happening and that its “rare” right? sounds like that from the blue post.

Hey all, thanks for all the data so far. There’s definitely something odd going on here. Please keep the reports coming - it’ll give us more data to point to. For those who haven’t run the test yet, check this post out:

We did a temporary solution by having an alt on an LA server invite everyone into the raid and then leave.

On Friday April 3, after drawing 24.105.32.254 and 103.4.115.155 as instance servers, I did several more dungeons on various Duskwood characters which connected to the following:

24.105.35.131
24.105.32.81
24.105.34.19
24.105.33.10
24.105.33.52
24.105.35.131
24.105.33.10
24.105.33.47 (Siege of Orgrimmar)

All with expected low latency but lo and behold tonight, I get into another Siege of Orgrimmar at 9:49pm server
(Maplesyrup@Duskwood) and got assigned to 103.4.115.223 with the expected high lag.

I’m surprised there doesn’t appear to be anything automated in the processes that detect anomalous behavior and alert the operator. Servers punting players on US servers to machines on the other side of the world shouldn’t be expected behavior.
