As Lindsey mentioned in the Admin forum, there appear to be some systemic outages happening today. DoS attacks or bad weather could be the culprits.
I'm having additional problems with my website anyway. I uploaded a bunch of new information on Sunday, but the site has reverted to the mid-September pages since being relocated to a server in Las Vegas. Now I can't get in to re-update the pages, probably because the new server lacks FrontPage support at the back end. So, things will be dicey until I can get it fixed through my hosting provider.
My email inflow is down by about 90% as well.
