It was horrible on Sunday, I concur.
Things have been a bit slow since the hosting changed hands, with a few days that either 404'd or lagged so hard it was useless trying. The days that it's working, it's fine, and I don't notice a difference. But the days that it lags.. ohhh boy. And it does seem to lag hard every now and again.
I've just assumed it's still hiccups from the server change. Hope you can get it sorted out.
