Got the "ask" popup notification right after first coming online today, shortly after noon Eastern time, and the update went just fine.
Slightly off-topic, and strictly out of curiosity ... anyone know if the order in which that notification goes out to users, on that 7-day server-cycle thing, is newly randomized with each new upgrade, or is it more or less constant? I seem to consistently get the notification quite early after a new version's release.
