I still get speed issues but the slowness has eased slightly since I posted in that thread.
If it's Google Analytics, you can probably block out access to the domain/IP with your router or a program. I use Avast Antivirus, that has URL blocking, I think I have GA blocked as it was causing trouble before.
I was under the impression this was a backbone problem though, as you can see in that thread. I still get timeouts from four Level13 IPs enroute to Namepros.com (according to tracert). That might explain why it's only effecting a limited number of users.
Most likely it is your connection and it's relationship to the datacenters connection. This page loaded in 4 seconds as the firefox page loader plugin shows.
