Hey, so, today I’m getting constant high latency 200ms on world but home is 36ms, I already bricked 2 +10 keys because of it … I cant cast spells to heal my allies, its delayed or like the server freezes, I can move around but actual game is frozen but I can still type in chat with other ppl seeing it … what is happening with the servers ? My internet is working fine, I have 15ms latency for everything, I can still speak in discord, my speed is stable 250mbit but in WoW today the latency is super bad. I tried everything, every step you provide in the guidelines and nothing helped it … I even talked with my internet provider and everything is fine on my side … I cant play the game when I’m free on weekend, great … The internet provider asked me if I know the IP address of the game server so they could try something, track and give me more information but I can’t provide it because I dont know it so. What more then the guidelined steps I can do ? 
It’s really sad, because last week and other weeks it was all good and fine, I had 36ms latency on both world and home but now its really bad…
Yes, today I’ve been having 200 world ms (19 home) in arena constantly with pretty much the best high end internet connection you can have nowdays - I never lag.
Been swapping between games just to make sure and yes, it is only WoW related. Probably had to prioritize Classic v2 servers cause who cares. I think it’s only related to some servers or group of servers. On Drakt’hul the game is unplayable for the entire day.
This is what you you get from a montly paid game enjoy. Make sure to preorder the expansion that comes up in few months with early access.
Same here, fluctuating from normal to usually 200-ish ms on world. Could rise to as high as 700-ish yesterday.
Repeats today and fluctuates between normal and high world latency (again 200-ish)
Would like to know what the issue is, or how to fix it, honestly.
