Grain change history: Outages with upstream providers causing instability

Grain reported a major outage affecting Grain Recorder and Recording Processing from 2025-10-20 13:09 UTC to 2025-10-21 11:30 UTC, lasting 22 h 21 min. AWS instance-launch failures prevented scheduled and ad-hoc recorders from starting; Grain moved recording to a new AWS Region, then deployed further mitigations after patch side effects caused continued recorder failures.
