Errors and Latency for Presence in FRA and BOM — ### **Problem Description, Impact, and Resolution** On October 22, from approximately 14:45 to 16:13 UTC, users of our Frankfurt \(FRA\) and Mumbai \(BOM\) points of presence may have seen elevated error rates and latency on Presence API calls. Other PubNub services were not affected. The issue began during a software update to the Presence service in Frankfurt. The new version was not compatible with the previous version while both were running at the same time. That caused Presence servers in the region to restart repeatedly, and requests that could not reach a healthy server returned errors. Our team identified the update as the cause and rolled it back. Service returned to normal at approximately 16:13 UTC. ### **Mitigation Steps and Recommended Future Preventative Measures** We are fixing the incompatibility before this update is released again. We are also adding tests that run old and new versions side by side before every Presence release, rolling out updates one availability zone at a time, and improving our rollback procedure so it does not run incompatible versions together.
