Sounds like you and I were both bitten by this issue:
http://linode.com/forums/viewtopic.php?t=4908
which for some reason doesn't show up in the RSS feed, or the "Forum Posts" part of the Community page, and is locked so that no replies can be posted.
This is another illustration of the need for something like "linodeemergency.com", which would be hosted completely outside Linode's infrastructure, and would be the official channel for outage information from Linode to its customers.
My Linode was basically unreachable, and since linode.com was in the same boat, I couldn't check the forums and I couldn't file a support ticket. I was completely in the dark.
Update: that Forum thread is no longer locked; apparently that was temporary to make sure only accurate information was posted while they were still investigating.
