Late Friday afternoon we experienced a subsecond power outage. All of our main servers are on backup power supplies and were unaffected. Other systems were not, and the fallout from this wasn't obvious until later in the weekend.
The most notable events were a switch going dead and several drives on the master science database (which are currently not on backup power) flaking out. The switch just needed to rebooted and several lagging tasks (including the one that regularly updates the server status page) were able to continue. We're now looking into cleaning up the master science database. We can currently create new workunits, but cannot insert new scientific results.
