This is considered bad manners if you have on-call SREs (or users).
Friday or weekend.
@Joshua Great, that makes sense. So David's changes were never actually deployed by themselves, and only went live after a deploy was triggered for unrelated changes, which happened on Friday.
Minor timeline correction: "PR was submitted Th night" should read "PR was merged Tues night". When it was submitted (3 weeks ago) isn't relevant, the relevant date is when it was merged, that was Tues night (link to PR).
lololololol
If this gets unresolved on a technicality, I will fully deserve it
@ian For this market, what I care about is that someone did something to prod on Friday, such that if they hadn't, the problem would not have occurred during the weekend.
@Stralor Yes, if the problem was caused by something someone did to prod on Friday I will count it here.
