Frequent spikes in World latency

Since around the time of the DF pre-patch I’ve been experiencing spikes of incredibly high world latency. That have recently reached the point where I’m not even comfortable doing any instanced content. The problem also crosses over to other Blizzard games. In Diablo 4, I keep disconnecting even though I would just have lag spikes during the Beta. In Overwatch, it is frequent lag spikes and disconnecting from matches.

I’ve followed all the common solutions listed in the technical issues stickies. I’ve tried two different VPN services to find they only decrease the frequency of the spikes, without them I’d spike within 10 minutes and with them I may get 20~30 before the first spike. MY ISP has also replaced all the hardware they’ve installed twice.

I’ve even tried different pcs, checking to see if my wireless worked better for some reason, and replacing the internet cables themselves. I’ve tried Ipv4, Ipv6, and changing DNS servers. Nothing has worked.

I’ve even made my ISP aware of the issue including traceroutes and WinMTR results.

At this moment, I’m sitting in Valdrakken with 24ms Home latency and 3721 World latency.

I’m including traceroute and WinMTR results.

Bump. Same on EU, and not a single response from Blizzard.

Issues still ongoing. Not as bad in Overwatch recently but still prevents me from doing anything serious in Warcraft or even being able to play Diablo IV.

Same, been having this issue since I started playing again which was about a month ago. Not sure if I’ll renew my sub if this issue will be on going with no support to help fix it besides the WoW community who aren’t the ones getting paid.

Still having the problem in all of the Blizzard games I’ve tried. Overwatch is still the only one where it is really manageable but even there I get frequent disconnects.

Hey there Hyacialle,

Thank you for reporting this with details regarding the testing you’ve tried! There aren’t any server-side issues that we’re aware of at the time of this message, and I didn’t find any known issues associated with your ISP or region. In this case we’ll want to have you run a ‘PingPlotter’ network test while a spike occurs in-game so that we can check into any potential network-related issues between your computer and the game server. Here are the instructions:

When posting the link in your reply, please replace the “.com” portion with “dot” (ex: share.pingplotter (dot) com/123456).

I’ve run the test during a period where my world latency was 1500+


Issue is still ongoing in WoW. Overwatch seems to have decreased a bit though.

And things have gotten a bit worse.

New Pingplotter result from tonight when I hit 2800ms.

Also results from using VPN at around 900ms (Express, location Albuquerque)

I’ve also noticed more disconnects and a serious delay when login back in after a disconnect. It is almost faster for me to close the WoW client and relaunch it to log in.

Hey there Hyacialle,

Thanks so much for providing those tests and the added context! My sincere apologies for the lack of reply. Based on the tests you’ve collected while on your LAN, it looks like the 4th – 8th hops consistently experience issues as you’re seeing the high latency in-game. The next time you experience the latency issues, can you temporarily swap to an alternate network such as a mobile hotspot? This will help confirm if the problem is isolated to the network.

If the latency then seems stable after switching to a mobile hotspot, at that point we can be sure that the issue is isolated to the primary network/ISP. In these situations, you will need to contact your Internet service provider since they’ll be equipped to diagnose the issue. When contacting the ISP you can request to speak to a “level 2 or level 3 technician” (and sending the PingPlotter tests to them) since the front-line representatives typically only have access to basic diagnostics and troubleshooting tools.

I hope this info helps!

Gave tethering a shot. I wound up with constant 300~500ms and frequent disconnects. Also tried a fresh install of WoW with no mods on another PC, still the same issue.

I’m hoping my ISP will come through.

Ive been suffering similar issues, followed every step, had my ISP out here to check on things, new router, new modem, but nothing. It has to be wow or bnet at this point. I have zero packet loss, even when the game and bnet disconnect. I hope the resolve these server issues soon.

Blizz, you know there´s many clients with the same problem, level3 nodes needed to reach blizz servers are dropping packets like crazy. You should investigate and get in touch with level3 (now CenturyLink), that is what we expect from you, get hands on the problem, not telling every user that is his fault…

Here my case:


Unfortunately, i’ve been having the same problems and nothing is seeming to help…


Same issue I had 52ms home and 1000ms world server while doing a Black Rook Hold key.

Try pingplotter, just let it run in background while you play, one tab for each US wow server, it will show pretty nasty red bars in the lower chart (latency, packet loss and jitter) when you get wow freeze cuz lag spikes.

Different countries, different ISP, different routes (getting in US through miami vs los angeles), all get the same problem…
