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.
