Summary
This is a Vibe AI auto-generated summary based on Slack thread + meeting discussion.
Description
A critical P1 incident was reported where the application server failed to connect to its backend database in the Kubernetes cluster. The outage caused degraded service for end-users.
Impact
Users experienced full service disruption in the application frontend. Transactions and internal API calls were non-functional. Admin dashboard remained partially accessible.
Root Cause
Application and database pods in the cluster were found to be in a CrashLoopBackOff state. Logs indicated intermittent connectivity and resource exhaustion. No restart policy was configured, and DNS resolution was delayed due to stale service records.
