Reverted to 6.5

Hey everyone,

After the upgrade, there were some persistent networking issues. I reverted the server to an image I had taken just before attempting the upgrade. You shouldn't have lost any data.

Next, I need to recreate the issues on a separate server, try to then tackle them there, and finally attempt another upgrade of prod to 6.6.

The networking issues were not present when I did a mock upgrade, oddly enough.
