The 403 errors are most often caused by google accelerator and other software that can cause unreasonably large number of connections to be opened to the server, which the server then considers a DOS attack. Visiting someone profile with a hundreds of games is a good way to trip it as the web accelleration software tries to prefetch all the links and images... A browser typically opens 2-4 connections to the server at a time. I have seen google accelerator open over 60 connections at one time.... and this server will give you a temporary IP block as it doesn't have enough memory to service that many connections.
When ioi upgrades the hardware, the DOS blocker will probably be removed (or at least adjusted to be less likely to trigger).
