We did a zone-by-zone reboot. If you want to send me the instance ids I will ask our team to see what happened. You can find my email in my profile.

How much delay is between zones? Some peoples services don't come up instantly. Perhaps when zone 3 when down, the users services in zone 1 hadn't finished coming back up.

They did a different zone every day, so ~24 hours.
