Problems: 

Power shutdown at ~00:18 affected the electric power supply of the Blanco telescope. Issue was identified and solved about half an hour later, but it was necessary to wait for 1-2 hr for the power to come back entirely and for the system to stabilize.

Another computer shutdown at around 03:11 - 04:20 causd the loss of another 1.2 hr.
