Technical Unusual Latency Spikes

[Gaan2]

Grettings, since few days i have problems with very unstable latency problems.
The problems starts only Around 6pm server time on Frostmane realm to me only,
Those problems start quite soft, but around 7pm the latency can reach even 2000ms and give me no info about what is happening for entire half minute,
It happend for first time Yesterday and repeated today
At morning i have cleared my cashe and folders with no effect
I even managed to stream the problem though discord to my friends and they watched how my game just doesn't respond connection wise, while stream was running flawlessly
It seems like my character in game still moves around, but it's My side that doesn't receive output of my actions
it is currently 11:30pm server time and it seems like latency calmed down back to normal value of 43ms, however a bit before 11pm it was 2292ms

It is not my connection problem as everything else works perfectly fine except WoW at this time of day, as well as i already restarted router not once, restarted PC and also played the game for entire day without problems.

Is there something wrong with part of Warmane? It seems like something os overheating causing those lag spikes to *me* but probably also few more players that i have no idea about. If that's not the reason then i am absolutley clueless what may be wrong as it definitevly does Not look like client side problem to me.

I'm facing the same issue, around 6:30pm server time server begins to lag severely. Can't raid at all nor do anything in game with 2000+ ping

BUMP
It happens still every evening and i Did tried today on a very fresh newly downlaoded wow copy, so it cannot be my Client side problem, but must be one of the internal servers overheating or something. My input seems to be somehow working, but i don't get informations on my screen on my end - Which means something in Warmane end have issues with Uploading new informations to user, while having good download of what users are doing.

Also btw, R.i.P. nice Server down issues today Ooof! i hope it is related to this latency problem, something overheating and restarts and Now i will have my fix after half week of No response from devs...
