As some may have notice we lost it again yesterday evening, unfortunately the logs are not showing anything so it'll be some trial and error changes to try to prevent it from occurring.
I have installed a new proxy server over the current webserver to try reduce some load, this forwards all requests through to the normal server but due to its improve handling of requests the main webserver can do less work overall, this is still being adjusted so please report any slow loading or other problems through out bugs board.
Apologies for all these problems, the easiest way would be to put another server in and load balance them, unfortunately at this time I cannot afford to do that. But the server is more than powerful enough, I just need to get it perfect.
