Likely reasons you're seeing this:
Network congestion. We're not hooked up the OC3 yet... we're on a temporary 1.5 Mbps line at the colo place. It can't handle the traffic. We should get a fast connection within a few days... I thought we would have got it sooner. :-/
I'm doing everything I can to find ways to get more bandwidth and offload parts of the site elsewhere for now. Sorry ... if it makes you feel any better, the servers aren't even breaking a sweat... it's just the network connection that sucks now.
