The site was horribly overloaded yesterday, which has caused all the downtime in the past ~20 hours. If you're having trouble viewing a page, try refreshing until it appears again. Please bear with me as I try to figure out what my options are. We seem to be fully back online now, thanks to the help of Matthew and DH tech support. You might notice that the Recent Posts and the Poll on the sidebar are gone at the moment - I'm doing a little testing to see their impact on CPU load. Hopefully I'll be able to re-enable them tomorrow.
