LDAS Has CRITICAL & Unknown Status. fw0 also INVALID

Andy L. contacted us via TeamSpeak to let us know that we have a local issue with LDAS (& "cluster"?). On the status page (https://monitor.ligo.org/ldg),

LDAS is RED/CRITICAL state, and it says to call Greg Mendell (just tried his cell, but voicemail not set up.).
LIGO Data Replicator is also in CRITICAL state, and it says to call Dan Moraru (just tried his cell, but voicemail not set up.)
Several DetChar systems with RED alarm states.

Also noticed that fw0 is INVALID on the CDS Overview (but fw1 appears to still be operational), and so I believe I remember Dave saying as long as we have one of these writers still operational, we should be OK----when they BOTH go down, it's an emergency.

The main 200 amp breakers for the computer power are tripped, so there is no power other than lighting.

Greg called me at 7:30amPST. Asked me to head out to the LDAS room (at the VPW), because he feared we had an HVAC failure because he could not ping any of his computers. He wanted me to see if the LDAS room was hot. I was not able to open the door with my card. I did hear a high pitch tone from within. I was also able to reach Greg on his cell (it must have been off when I tried calling earlier).

I notified Bubba and John about the situation and they will check out the room.

Greg is going to contact Dan Moraru to have him check out their system.

I gave Ed (incoming operator) an update on the status.
