QUICK SUMMARY:
When I got in the ISI ITMX(BSC3) watch dog had been tripped and already reset via software. I called Jim and let him know that there was not an earthquake that caused the watchdog trip it but a CPS glitch as Tj pointed out in his alog
He asked me to power cycle the 3 BSC3 ISI Interface chassis in the SEI-C6 rack via the 3 DC power switches on the back side of the chassis .
Lockloss from a 13 hour lockdue to a CPS glitch.

While typing out this alog the IFO has been locking and has cycled through check mich fringes a number of times already, I'm doing an Initial_Alignment now.
