About 27 hours ago the website was taken down by my hosting service for CPU Overuse. It appears to have been a random bug with the forum software and was not malicious or intentional.
After not hearing back from my hosting provider after a few hours I set up a copy of the website on another server (without the blog or forum) and changed the nameservers to point to the new site.
A few hours ago the original website was restored and the nameservers have been switched back. Depending on who provides your internet and what DNS server you use it can take anywhere from a few minutes to many hours for the nameserver record to be updated.
Thanks again to Deoxy99 and Chaotic Cow for letting me know there was a problem with the site.
Please let me know if you have any questions.
