Since the 2.0 relaunch they've added new game servers, added new instance servers at least twice. They're throwing money at the congestion issues. This particular problem must be a routing issue somewhere that wasn't noticed until the DF servers were put back under load. The Aurum Vale thing is different and I'm fairly sure is related to room 1 farming and the stupid stress that puts on the DF server when it has to load and unload the same instance over and over every 5 minutes. 100 instances up at a time is no problem...even 100 AVs...the issue comes when the servers are constantly refreshing 50 of those instances at any given time due to Room 1 spam. The generation happens fast but takes up a HUGE amount of CPU power Im sure. So instead of having 100 instances up and maybe generating 4 or 5 new ones every few minutes it's having to maintain those 100 instances AND be loading more like 30 or 40 new ones every few minutes.
