Now at 9:50pm CST Saturday the power has once again gone down due to severe weather. UPS will run 30 minutes and then systems will be down until power company comes out and repairs. That could be until the next morning.
Email and DNS backups do exist, delayed mail will be delivered and accessible once power is restored and systems are operational.
UPDATE: Power is back but authentication is not working again (despite manually shutting the database down before automatic shutdown!) I have blocked dependent services until I can go out there tomorrow and fix it. In the mean time, mail will continue to deliver to the backup mx and you’ll be able to retrieve it tomorrow.
UPDATE: Service is restored. All should be functional again. Thanks for your patience.
UPDATE: My bad this afternoon, fixed now. :(
