Update: Planned Power Outage - July 23rd-24th, 2014
Due to necessary electrical repairs at the data center, we need to shut down some servers for a brief period the morning of Wednesday, July 23rd, then again for a longer period throughout the work day of Thursday, July 24th. All the SETI data servers will be unreachable during these outages. The work should be complete by Thursday afternoon, and all services back on line shortly afterward. 22 Jul 2014, 21:01:05 UTC
