Looking at the trend data, the NPRO switched off on July 23rd, 2019 at 10:33:46 PM local time (1247981644 GPS time) and was off for ~26 minutes.
Attached are plots of the NPRO, front end laser, and 70W amplifier outputs.  The pre-modecleaner output and high voltage power supply output
for the same time period is attached (PMC.png and PMCKepco.png).  The pre-modecleaner was not operational again for approximately another 4 hours
and 7 minutes.  The FSS hadn't really stabilise until another ~37 minutes had passed (FSS.png).  The ISS was not on until ~11.5 minutes after
the pre-modecleaner was restored (ISSLag.png).

    The PSL was not functional until July 24th, 2019 at 2:57:42 AM local time (1247997480 GPS time), some 4 hours and 24 minutes after going
down.

    Otherwise the PSL seems okay.  It might be worth checking the performance of the servos at the next opportune maintenance Tuesday.
