Literally left the house and the sites went down. Just got back home, looking into issue now.

UPDATE: Servers in the Atlanta datacenter are down. I’m unable to access them remotely. Waiting on datacenter.
UPDATE 2: Router hardware failure in Atlanta datacenter. No ETA on fix.
UPDATE 3: Pinpointed the issue to a wide spread power outage in the datacenter which caused several cages to lose power entirely. Backup generators failed. They’re on the floor working to restore power right now, some cages have already come back online.
UPDATE 4: Sites are slowly coming back online. Not quite there, but almost!
UPDATE 5: It appears things have stabilized. I’m already working on a solution to prevent this from affecting us again in the future.
