"500 Internal Server Error" now fixed

As a lot of you noticed, the websites gave a "500 Internal Server Error" today, and were unreachable for quite some time. I am not entirely sure exactly what caused this, but my webhost told me it was due to "a network event that was impacting our servers". 

Anyway, it appears that everything is now up and running again, the links seem to be working fine and I expect that my webhost has solved the issue ^_^
