They previously had a message that Linodes would be returned to their previous state. Mine was rebooted. Just FYI. Check your DBs and all that usual stuff.
Mine was rebooted 2hrs ago but still cant access it.
That happened to mine, too, though not for as long.
I bet they had some host filesystem corruption and they're dealing with it manually.
Thanks for the encouraging words ;) Still not up, 5+hrs outage so far...
EDIT: it was up, but the network interface was messed up for some reason. Rebooted again and its ok now.
