I have seen quite a few threads here about DB errors, and people wondering why they occur. These happen about once a week. The reason for these occuring is when the Site's CMS(Content Management System) is being updated. During this period of time, you will not be able to access the main site and your RSS Feeds will not load. This is only temporary while the changes occur, and the admins try and get everything back up as soon as possible. Hopefully, this will be stickied so more people will know the reason why.
