They know what are the problems and what they need to fix it. It they can’t get the hardware to do it. They even offered way over market prices to get it but no luck.

They will add a new DC when they can get the hardware, but nobody knows when that will be. SE can’t use generic servers either as the game is optimized to run on specific hardware.

In my professional job, if somebody asks me do a laptop, I have to tell them to wait at least six months, yes six. That is how bad things are. Servers are much much worse.
