Is host56 down?
I can't reach my node, and I can't log in to host56 either:
$ ssh host56.linode.com ssh: connect to host host56.linode.com port 22: Connection timed out
However, the control panel shows it as "running".
The job queue doesn't show anything in the last two days.
Judging by the symptoms, though, it appears to be either a firewall block or a routing issue on your end.
Why didn't my linode on host 56 reboot itself?
How long has it not been running?
