> Anybody familiar with these systems know why they would do an update like this at 3pm on a Friday

As an insider to the technology industry, I would surmise the technical reason for it is that they didn't want to work over the weekend.

(Yes, this comment is tongue in cheek, but not everyone follows the "don't deploy on Friday" rule, even people in mission critical fields.)

Isn't that exactly what they did? If you do major change on Friday at 3pm you likely will work over weekend.

		There is also a real possibility they did this many times before and it worked. I don’t really get it: if the thing would have broken on a Monday night and it would take a day to fix would that have been better?

		That's why you don't deploy on a Friday. :)
