JustCall incident

A subset of users unable to make and receive calls

Resolved after 12 minutes, affecting Outbound Calling and Inbound Calling, on March 9, 2026.

postmortem Mar 09, 2026, 12:35 PM UTC

We experienced a temporary service disruption that caused a subset of Voice requests to experience elevated response times and intermittent errors. This occurred due to a brief internal connectivity issue within our infrastructure, which prevented a subset of requests in that zone from reaching healthy service instances. This seems to have been caused by an underlying GCP issue with GKE in the region where our system is hosted. Connectivity was restored shortly thereafter, and the system automatically recovered as traffic resumed normal routing.
