That makes perfect sense to me now. If the code is being updated it would make sense not to try to process data at the same time, so there would be nothing to see apart from updation delays and any glitches that would presumably be ironed out by all the testing or the following weeks maintenance. So nothing to do with moving the database after all.

It's all very clever stuff. Delays in processing stored data would explain why the maintenance days often seem to be low earners, but a couple of days later there might be an above average day.
