they're *only* instancing newbie zones. i.e. Greater Faydark, Steamfont Mountains, Nektulous Forest, Toxxulia Forest, etc. and none of the newbie dungeons are instanced. there's been about 60-70 characters in blackburrow steadily since thursday night.
server has been at max capacity consistently, too. some people report having to spam the "PLAY EVERQUEST!" button for hours before they get on (i've been getting on within a minute or two every time, though, so IDK maybe they're just unlucky or dumb). as a result, once people got online, they were just going AFK when they were done playing, rather than logging off and potentially not being able to get back on later. people bitched about this, of course, because hardcore everquest fans bitch about everything. so the devs wrote some code to boot AFK people, took the server down for 30 minutes last night to patch it in. nothing blew up after that. i thought for sure it would introduce some new, horrible bug, but it went fine.
hopefully they open a second server, though. the only place i've found so far that isn't atrociously overfilled with players is Befallen.
