Hi Lab,
The system is mostly restored. Some services I am still restoring, but
primary services are available.
Yesterday evening, the power in the SCS machine room was severed. I
have been told that the outage occurred due to an incorrectly performed
test on the new fire suppression system. The test was performed by an
external inspector. The power interruption was long enough that all of
the backup batteries went dead, and took the entire system (and Wean
Hall 3611 SCS machine room) completely offline. That said, you should
know that any and all compute jobs that were running have been
terminated since every last server went down. It is likely that you
will see (or have seen) a notice from SCS explaining the unexpected outage.
Normally, I receive a call from SCS when any of our public facing
machines go down. This time, however, I received no phone call, because
they were in crisis mode themselves to get things like DNS, mail, and
AFS restored. In crisis mode, their policy is not to deal at all with
'project servers' until the crisis is resolved. They are still here in
droves in the machine room finishing up their recovery.
Due to the entire machine room, including networking equipment losing
the power, I received no notifications when anything went down.
Additionally, I did not get my email until this morning, which is the
first I had learned of the problem. As a result of this incident, I
will be setting up extensive off site monitoring, so that even if all
else fails, I will still be notified of issues in a timely manner.
I recommend that everybody store my office number (412) 268-8939 and
mobile number (412)-229-7356 in your cell phone. Please feel welcome to
call me if you see any extended unannounced, or unexpected down times.
Please don't call my mobile during off-hours for user requests and
things that can wait until the next day - use email for that. Please
understand that there are just too many of you, and I'd be getting calls
all the time at home and while out.
Again, system is 95% restored. The 5% that is still to be done is not
likely to affect most of you.
Cheers,
Mike
