Does backblaze ever power cycle the drives (either on a schedule or due to planned/unforeseen circumstances)?

If so, it would be interesting to know how many drives failed on the day of a power cycle vs days with no power cycle.

I know other providers have found that "power cycle days" can be 100x more deadly for drives than "non-power-cycle days". It can have a massive impact when estimating data loss probabilities - since unforseen power cycle days tend to impact more than one drive at a time...
