There was a short (less than a minute) power interruption at the data facility which houses the majority of M5Hosting customer servers. This caused all of the servers to reboot.
It is too early to know the root cause. The majority of customer servers came back up right away, as expected. However, some did not come back up as expected.
We have our entire technical staff at the data center working on the issues as quickly as possible.
There will be a complete post-mortem available as soon as possible.

Thank you for your patience and trust in us.

Sincerely,
Mike

UPDATE 13:45 PDT: There has some packet loss, which may be related to the power event this morning.

UPDATE 15:30 PDT: All network issues have been stable for a few hours. Only a few servers which have hardware failures (ie: failed power supplies or hard disks) remain down. Tech staff are addressing them as quickly as possible.

UPDATE 17:34 PDT: The failed power system components have been replaced. The data center will be transitioning off backup power and back to SDG&E power at about 18:00 PDT. Tech staff remains on site to address any issues that may arise.
