#March 29: Sprite creation errors in SJC and AMS (14:36UTC)

Sprites are provisioned from pools, which are our regional buffers for spinning up the underlying apps and machines. This was a brief incident where the pool monitors, responsible for replenishing these pools, weren’t running in a couple of regions. Once the monitors were up again, pools refilled and sprite creation returned to normal. Ideally we catch this before the pools are empty, so we’re adjusting our alerting to make sure that’s the case.
