Host unreachable after maintenance
Tonight my linode was reset for scheduled maintenance. It didn't come back up. I logged in using Lish and the node could not reach any other node. For example, ping 8.8.8.8 showed Network Unreachable.
After a reboot everything worked fine again. How can I prevent my node from going Unreachable after maintenance?

It's hard to say for sure without knowing which service failed to start after the host maintenance, but I would recommend going through our Reboot Survival Guide which should help configure your services to start after the maintenance.
If the issue continues after you run through the reboot survival guide, I would recommend logging into your Lish console before issuing a reboot so you can determine which service did not start after the maintenance.
@hmorris Thanks for the pointer. Journalctl only seems to store entries from the latest boot so I was unable to analyze the problem. It might have been related to an error in /etc/network/if-pre-up.d/firewall.
Hey andomar,
I would also recommend taking a look at this answer for some additional troubleshooting steps to see if those help point you in the right direction.
