For their servers? Yes xD
My theory is that they run multiple servers on the same physical server. So, it isn't only those 63 players that count. EG with 200+ online players is even worse. The problem here is that more than 500 players (an idea) tried to access multiple servers at the same time (because of era starts - which wasn't clearly well thought given their processing capacity)
That means they are almost unmanaged because you can anyway balance resources between Virtual Servers.
