I'm not sure whether this is a Quic issue or a Blizzard issue, but figured I'd start here.

I normally sit at around 150 ms to WoW (Wild Growth SOD server). This morning I logged in before work, and the ping was in the high 200s and the game was noticeably laggy. I saw that Quic had known issues so I didn't worry too much.

I got home a little while ago and saw that Quic reckoned the problem was fixed, so I opened up the game... and it's still sitting around 285 ms and not running well.

Blizzard seems to have deleted the official list of IP addresses but Wowpedia reckons that 12.129.209.68 and 137.221.105.2 are the addresses to test. Both of those yield a normal ~150 ms when doing a traceroute, and the latter is giving consistent pings (the other address doesn't respond to pings). Pings to BNG1-AKL2 are a normal 10-11 ms.

Any ideas whether this is a Quic problem or a Blizzard one?

There was maintenance over night and some minor work done on a faulty element. There was also some other work to fix another WoW issue but for Sydney as it was taking the scenic route.

137.221.105.2 actually gets an end point and I can see it's going via 1299 (I and many have very very opinionated feelings about 1299).

The former is via cogent.

Need an actual game IP to test, but also the game could determine latency in a lot of ways.

I use quic. They're a great ISP for techies. Use my referral I get money off my bill! You can get the setup fee waived too via this code when you order! R177510EBNVXP

I wasn't home last night and I was hoping this would resolve itself overnight, but no such luck :(

I'm at a bit of a loss as to what I can do, if anything. The server I play on isn't listed on the page linked above, and while netstat (which I'm not familiar with) claims to see a bunch of connections to "6.122.117.34.bc..https", whois tells me that that IP address is registered to the US Army?!

Can pass it along to the team, really need a testable location (ip) to troubleshoot it. Assuming this is a US/Asia realm rather than AU?

What is the realm name?

Yep, it's a US realm, Wild Growth. Unfortunately most players jumped ship from the AU realms a while ago and my guild was one of them.

I'm not sure how to get an IP address out of it, other than my fumbling around with netstat.

Try joining the game on the realm, and ask in the general chat - someone may know.

Nothing useful from chat, but after doing some reading about netstat I've found 137.221.105.232, which appears to be from the correct range so I'm going to assume that that's it. Pings to it sit around 150 ms, which is about what I usually get when playing the game. Could this indicate that the reverse path is the problem? Blizzard used to have a tool called Looking Glass for troubleshooting this sort of thing, but they've got rid of it :(

I've just performed a RIPE Atlas measurement from 100 probes in New Zealand, which is giving a mean RTT of 154ms to 137.221.105.232, lowest 131ms and highest 231ms.

Given fluctuations dependent on actual location around the country, I'd say the ~150ms you're seeing is expected for New Zealand currently.

To clarify, 150 is about normal. The problem is that I've been sitting around 280-300 for the past couple of days (in fact it's gone up to 332 at the moment). While my pings to the IP address look normal (~150), the in-game reported ping is much higher and the game is noticeably laggy.

@behodar I’m seeing ~150ms on the other Vetta tests there. If you’re at 300ms there may be something up on your end. You using WiFi?

Nope, Ethernet. I would have thought I'd be noticing more oddities if the problem was at this end, e.g. pings to other services look fine, and the old AU WoW server is fine. I also tried a different US server (Dreamscythe) and it's exhibiting the same problem.

I've just tested on a different computer and it's doing the same thing. I've changed nothing in my network configuration (it was working fine one day, I went to sleep, then it was laggy).

Does anyone in this thread have the game client?

I'm going to log a support ticket with Blizzard and see what happens. [Edit: Done]

Blizzard has come back with this:

"I can confirm that we’ve received a few similar reports over the past couple of days from players in your region, so you’re not alone in seeing this change. While we don’t have confirmed service issues on our end at this time, situations like this may point to temporary network congestion or routing challenges that can affect certain regions or ISPs."

The rest of the message is basically "be patient", so hopefully it'll get sorted out soonish. It looks like it's not a Quic issue specifically, but thanks to everyone who's helped :)

PS. Something I should have said earlier: the rest of my guild (~20 players, mostly in NZ) is not having this issue, but I think I'm the only one on Quic.

This is still an issue as of this morning. I contacted Blizzard again last night to see whether they had an update, but was just told to contact my ISP.

"If you continue to experience issues, please let your ISP know about the specific server you're connecting to [Wild Growth], and they can reach out to us if needed."

I posted on the Quic Discord yesterday in the hope of finding another Wow player (just to make sure it's not just me), but as of this morning hadn't found anyone. Are Quic and Blizzard able to talk to each other and try to track this down?

The problem is without an example IP address it’s going to be very difficult to diagnose.

As I’m not a Warcraft player it’s not something I can easily get and I suspect many others are not either. If you’re able to get an IP then we can start with that. You could also perhaps post in the Blizzard forums?

I explicitly asked Blizzard whether 137.221.105.232 was the correct IP address and they didn't respond. In fact, they went further than not responding: they edited my support ticket and redacted the question out.
