Sep 29 Incident Update: Read-Only Repls
Replit experienced a significant outage on September 29th when an incomplete build of their new storage system was inadvertently deployed to production. This caused approximately 2.5 hours of Repls opened during that window to become read-only or non-functional. The company has since fixed the root cause and, through multiple recovery iterations over several days, has restored 98% of the affected Repls, with efforts ongoing for the remaining 2%. Replit is implementing new deployment guardrails and automated canary analysis to prevent similar incidents in the future. AI
