Noticed that the server took a dump last night, not letting me shell into it (showing 'permission denied when I shelled in the night before with an ssh key). I have access via an admin interface, took a look at the logs and didn't see anything. Ended up trying to restart the server...it booted up fine (I didn't see any errors) but the system was still acting hokey.
I can't access the webserver either, as I keep getting 'forbidden' errors.
It may be down for a few days while I find out what's going on.
