Shortly before leaving work today, I upgraded the SSH server on the server I have colocated at the office, then rebooted it for that to take effect. It was taking a little longer than normal to come back online, so I stop by on the way out and it's apparently doing a file system check... after a year, it was probably due for one. I get home, and an hour or so later it hasn't started back up yet... I'm thinking this is taking too long, and starting to fear the worst.
I call up a friend of mine on the building's IT staff and ask him if I could get into the computer room after hours to check on it, and he agrees to help me out. Within 20 minutes, I've got the problem
I owe him one.
