Can't get on the server = Can't restart without SSH.
Indeed... I used to have SSH... 
Actually, I used to have it on Qaz's old machine - forgot we moved to the super-computer.
However, now's another time when having server restart access would be handy... (server's down again).
EDIT: It went up again, but went back down a few mins later. :-/ Any clue in the log files what's happening?
The oh so very smart people at the hosting place thought it would be a really nice gesture to use some good enterprise backup software made for linux to back up our stuff.
Never mind the fact that our own backup scripts (tarball/kick off to the HDD) run at midnight PST every single day in addition to our 5-min backups to the SSD without bothering anything, their program halts EVERYTHING on the server for 10-20 minutes to back it all up. This includes, among other things, the servers.
The servers don't actually go down, they're held in stasis until the program is done. The program runs at more or less 4:20AM PST every day, and has thus been dubbed the "Stoner program" since obviously someone had to be high to install such a thing without asking us. (plus, you know, the numbers)
Think CloudFlare levels of stupid.
Doesn't hurt anything, and it does flush out SWAP/Cache for us, but it's annoying as hell, especially for people who don't live in North America.
