There was a major power outage on Tuesday evening that affected several buildings here on campus including the entire Space Sciences Laboratory. Power has been restored this morning, and we are slowly getting the project back on line.

More detail (from Jon - another systems administrator here at the lab):

Power failed when there was a short in the power distribution lines that feed the hill buildings [including Space Sciences Laboratory, Math Science Research Institute, Lawrence Hall of Science]. The short occurred because of deterioration of the insulation on these power lines, which are buried in a conduit in the ground. The power distribution lines are thousands of feet long, originating in a substation at LBL below LHS. Most of this conduit only contain one power line, but we were lucky in that the section that failed had two power lines in it, so the electricians could just utilize the second unused line to restore electrical service. It was an arduous process finding just where the short was, since they had to disconnect one segment at a time and test it. This is why it took so long to find and repair.

To get it all up and back on line from scratch in two hours was a major feat of teamwork, I take my hat off to you and the lads, well done!


Thanks. A mixture of "all hands on deck" and incredible luck that nothing really got corrupted/fried when the power suddenly disappeared. There are some RAID resyncs happening at the moment, but looking good thus far...

Glad to hear nothing got fried.
Frying leading to corruption is one of the biggest hazards of a big mains cable shorting, especially one that is of any decent length.

Well done to all.

Uploads, reporting and Downloads are all working here. Even SETI Beta is working !

I noticed that SSL is over 50 years old now, are the cables a similar age ?

Haven't been able to Upload to SETI via BOINC. Are there still issues with connecting to the server?

I just managed to report 181 tasks and actually got 1 (one) downloaded in return. That's okay though, I'm just happy things are moving.

Thanks to the scientists for a great job! +10,000!

and thanks for the update, I think some of us thought the world was ending. :-)

Glad to see things coming online, and people be patient; it just came back online after days of being down, I bet it'll be 24 hours before everyone's machines report and start crunching (getting work) again.

Nice job on the restore, "everything takes longer than it takes".........keep up the great support.

Until I saw the power outage news posted on the Net, I thought maybe the signal had been found...........Oh well, back to work

Am I reading this correctly that when the power went out the servers all
insta-shut?

I am shocked to learn that a facility like this has no backup...even to do a clean shut down.
