We've been having two ongoing issues tonight:
The forums have been slow tonight and going up and down due to issues at our datacenter. Our provider was having problems with one of it's uplinks (Xeex Communications). They've temperately rerouted service to another uplink and got everybody back online. As jamie has stated earlier, problems at our provider are out of our control.
The second issue I think is with Apache. I'm not sure if it is a configuration issue or not, but some people are experiencing random white screens and error messages saying "hacking attempt". We are testing out lighttpd (another web server) and the problem is not occurring so the problem is likely Apache.
In the meantime, sorry for the bumpy ride tonight. Not quite the best way to start off the new year, but we'll have everything back to normal soon enough.
