Four cabinets went down due to power issues caused by the storm. Storage controllers for /work-common are also affected.
Hexagon was started without /work-common filesystem.

We are trying to fix issues with the filesystem controllers and get back the filesystem in production as soon as possible.

Update 2016-12-27 14:50: Troubles with /work-common storage controllers were mitigated and filesystem is taken back online. Hexagon had to be rebooted today at 14:15. All systems are up and functional again.
