Electrical storm power glitch rebooted h1susaux[h2,ex]. PSL is having problems.
After the watchdogs were reset a lightening strike caused a power glitch. GC UPS reported going into and off of battery power.
h1susauxh2 and h1susauxex went offline, turned out they were rebooting themselves and came back after a few minutes.
PSL is in a bad way, Ibrahim is calling for support.
The lights in my house flickered at the time I saw the sus-aux machines go down. We have been having a storm roll over us for the past hour, moving from Oregon northwards.
Ibrahim is on his way to the CER MEZ to reset the PSL REFCAV high-voltage supply.
Back on.
Here are details of the power glitches due to the electrical storm Monday night. We had a large glitch at 21:51:26 followed 5 seconds later by a smaller glitch.
