Come on guys
seriously 19:00-23:00 is peak/rush hour for gaming, no matter what game, in 2010 riot separated EU server to EUWest/EUNEast, they explain it that EU have pretty much one time zone (USA have 4, so the +300M people come home different hours) so VERY many people log in at the same time, and it is very hard to fix, and… you know most guilds raid at 19:00. and now you have remix+anniversary active, too.

real life example: city roads/highways, most of the day it is pretty “empty” you can go max limited speed , but 2-3hours every day you have peak/rush hour, because majority end job shift and go home
or during christmas/holiday season, when city roads is full of cars because people are shopping
or read about “Hollow Knight Silksong has crashed Steam, and other eshops

it is fixable, it is not cheap and sometimes it is not good way to spend money(everyday VS holiday peak hour), but same as greedy politician, you have greedy shareholders, which they don’t want to pay money for more roads/servers/infrastructure
should they “rent” more servers during big events ? Definitely yes, is it possible to “rent more servers”? probably; will they? no.

so on scale how much is this Blizzard/Microsoft fault is like 50%/50%

i had no similar problem in corona times when there was 3x more players,happening last 10 days.
