- postmortem Sep 09, 2026, 08:38 AM UTC
**Introduction** On September 3, 2026, from 14:51 UTC to 16:17 UTC, the in1: Cloud - India region was unavailable. During this period, customers were unable to access or navigate around the platform. **Root cause** On September 3, 2026, during a planned renewal of security certificates for our services in the India region, an incomplete certificate bundle was applied. This caused authentication and validation services to be unable to verify the secure connection, which resulted in the platform being inaccessible. **Recovery** Our engineering team identified the issue and took immediate action. We reverted the custom configuration to the platform's managed secure certificate service, which successfully restored connection validation. By 16:17 UTC, the issue was fully resolved. **Corrective and preventative actions** We are implementing the following actions to prevent recurrence: * We are conducting a thorough audit of all security certificates across our environments to optimize and standardize our configuration management. * We are transitioning to managed certificate services to minimize manual configuration requirements. * We are implementing automated full-chain validation checks for all future security certificate updates to ensure complete integrity prior to deployment. We apologize for any impact this issue may have had on your business operations. We are continuously strengthening our systems and procedures to ensure we avoid future disruptions to your business and users.
