Some users could not access Hex projects during a critical Main site outage starting 2025-08-20 17:00 UTC, lasting 1 h 26 min and resolved at 2025-08-20 18:26 UTC. Hex implemented a fix and attributed the cascading failure to a feature flag, deployment timing during peak traffic, and inefficient database connection management.
