Severe packet loss every night on a Blizzard Server

Hi there, every morning on a specific Blizzard node there seems to be severe packet loss the makes the game unplayable. The IP address is: 137.221.77.35 - ae1-br02-eqpa4.as57976.net.removeThisPart

Here is the pingplotter graph for it:

(nevermind I can’t post images, but there is severe packet loss)

As you can see on Hop 7 there is no packet loss, but on Hop 8 there is severe packet loss. Here I am only talking about the packet loss that carries through to the final hop and NOT the evenly spaced out packet loss on Hop 8 that doesn’t carry through.

These times are in Central Standard Time - So just add 7 hours to whatever you see here. The packet loss occured 8:10am - 9:45am Paris time.

When the packet loss occurs (red lines), the game is unplayable for me. Please have your network engineers take a look at that node.

Thanks

Hello Javthechad,

Is it possible to run a WinMTR for about 10 minutes or so, and paste the results in Pastebin or a similar site?

Hi Vossprey

The packet loss has stopped, but it always happens at around 8am - 11am Paris time. Running a WinMTR wouldn’t show the results. Is it possible for me to send you a picture of a pingplotter graph?

Hello Vossprey,

I have the same issue as Javthechad, since yesterday it seems.
And currently have it right now.

Please see below the WinMTR result on a pastebin :

One of the ip address with heavy packet loss are exactly the same one Javthechad talk about.

That’s really not enjoyable to play with 3000ms ping…
I’m surprised that I’m still connected to the game.

Thank you for you help ! Hope it will be fixed soon enough :grinning:

I think those are the same ip’s previous posters mentioned.
It is my second try to reach out to blizzard about this issue, first one was a ticket couple days ago where i attached my dxdiag, msinfo, mtr test and looking glass test all showing an issue around netherlands blizzard ip i think ?.

All i got was a generic answer to reset router flush dns update drivers etc, I’ve done all that plus a fresh windows install.

My Pc is now fresh with all new drivers and only wow installed the pastebin i attached earlier in my post is from 30 minutes ago the issue is still there.

Sorry for my weak English Please help :frowning:

I’ve been getting regular disconnects (most straight after logging in) and on WinMTR I notice the following:

WinMTR:
ae1-br02-eqam1.as57976DOTnet

et-0-0-3-br02-eqpa4.as57976DOTnet

On everything else the ping times are averaging between 10-20 with worst outliers still remaining under 80.
