Thrall EU Server - LAG Spike

Support Technical Support

Hi everyone!

For the last 2 days, I’m experiencing LAG spikes in my WoW Retail connection.

I play in Thrall EU Server and my ping is something like 30mS but suddenly the connections stop and come back after 3 seconds in the worst case.

I live in Germany, near Munich. My connection is a VODAFONE 200Mbps by cable. Other things work normally.

There’s something I can do?

Thanks in advance guys! Have a nice Easter =)

Hi! I’ve see in other posts that the GMs ask for using the “Blizzard Looking Glass”. So, here it is:

Question. Is this lag spike you’re talking about where the entire game seems to freeze for a second OR where you’re basically walking in place for a bit and then afterwards everything just speeds up to get back to normal?

exactly this one… strange, appears to be like a short internet disconnection without DC

Based on the connection files here, the traceroutes are showing a slight variance but nothing too worrisome. The MTR tests however are showing a consistent packet loss at the last step. Any packet loss between 0% and 100% is cause for concern and this seems to happen when your Internet Provider is moving your connection out into the real world.

The packet loss doesn’t show on the very last MTR which tells me the issue is intermittent which would match up with what you are seeing happening ingame. Either way, the best thing to do is to show these results to your Internet Provider and highlight the packet loss shown in the MTR tests.

Hope it’s something that can easily be sorted out so this issue you have will be sorted :slight_smile:

Good morning Jingoraitin =) Thanks for the reply. I’ll do this exactly now. I’ll leave the post open and try to update what I find here. Thanks!

Just another thing Jingoraitin: I installed the MTR in my computer and leave it running for a while and I got this:

The last step is the 185.60.112.158, right? This is the target IP of Blizzard EU servers?

Something more that you can diagnose with this?

Thanks in Advance and sorry for the inconvenience xD

No inconvenience at all! :slight_smile:

Just bear in mind that new test you did just now is working in reverse order to the looking glass test. The Looking Glass test is going from Blizzard to you whereas that new one is going from you to Blizzard. So in short, yes, the last step of your new test is us.

That new test still shows heavy packet loss early on (the number after the server name / IP) but it’s also showing packet loss on Blizzard servers. I’ll note that and notify the appropriate peoples but it’s still worth highlighting the issues early on to your internet provider too :+1:

Ok! Got it. I’m trying to contact Vodafone - let see what I can get from then =) Thanks again!

Hi! I’ve seen in Vodafone forums that they use a lot of the “PingPlotter” program to check connectivity.

Do you have any idea of what means, in this case, it’s package loss in the destiny or the hops? Because as you can see in the picture, there’s a lot of losses during the way to destiny.

[Photo of PingPlotter] (https://ibb_co/0f5j54z) -> just change the “_” for “.”

I tested 3 available EU servers IP - How they are chosen in the real connection because some of then are better than the others (in package loss question).

Thanks again for all the help =) This question it’s really annoying me xD

Just to keep this post alive.

Sorry for the delay in getting back to you there.

Pingplotter is just another type of connection test much like the MTR test. It tests for packet loss along the way aswell as the latency in getting there. Based on the picture you linked, the packet loss is something that is happening on the “hops” going to the destination.

Each line in that test is called a hop and not all lines are showing packet loss. If you look under the % column that’s the one that is showing packet loss. Anything that is not 0% or 100% (as this just means the server is blocking the test) would be cause for concern.

If Vodafone prefer Pingplotter, you can show that image to them and they will be able to see the issues :slight_smile:

Hi Jingoraitin! There’s no need to apologies haha

It’s getting a little bit difficult to contact the guys but I know that in this “pandemic” situation, it’s something that can happen. I’ll keep this post open till either I find something or the guys.

Thanks again!
