Front change history: 2025-04-29 Application unavailable for some customers

Front reported a critical App outage affecting roughly 3% of users, a subset of US-based customers in us-west-1, from 2025-04-29 23:54 UTC to 2025-04-30 05:43 UTC (5 h 49 min). Human error during planned maintenance made one database shard unrecoverable; Front restored it from an up-to-date backup and caught up missed messages.
