We posted this update earlier on Facebook:

<< Our webhost is reporting a major outage, due to a cut in the fiber between our webhost and a major network hub. The webhost is working to fix it; they don't have an estimated time for getting the connection back up, but our best guess at the moment is that they'll get it up by 5 pm EST. >>

They were able to restore the connection 10 minutes before 5 pm, and the site has been back up since then! Sorry to everyone for the downtime, and thanks for your patience!!
