Corruption in test execution index.
Monitoring - We have re-indexed most of the tenants over the weekend and the application now looks stable. We will continue to monitor for the next 24 hours for any problems.

For the few remaining tenants, the re-index process in still in progress. We will communicate the time to complete individually via our support teams.

Intermittent app downtime
Resolved - The fixes are stable. We are not seeing 504 from Elasticsearch.
Oct 7, 16:47 IST
Monitoring - Update:
On 31-August-2026, some Zephyr for Jira Cloud customers saw slow responses and 504 (Gateway Timeout) errors. Actions like updating test executions and running ZQL searches could fail or take longer than usual.

What happened
A large surge of background Jira events came in at the same time, mostly from creating Jira versions, with some from issue updates, component creation and sprint deletion. Each of these events made several back-to-back calls to our search service. Together, they used up all the request-processing capacity on every server in the service. Because of that, regular customer requests had to wait in line and some timed out.

Current status
We have found the root cause and have deployed one set of fixes:
Removing repeated and unneeded search calls when Jira versions are created
Caching information that rarely changes so we look it up less often
Grouping search operations into fewer calls

We are monitoring these changes, while we work on the other areas where the same issue can re-occur.

We're sorry for the disruption. We'll post another update when the pending fixes are deployed.

Update - Following the August 31 occurrence of this incident, we identified Elasticsearch as a potential bottleneck causing thread starvation in the middleware layer. We subsequently introduced additional monitoring and telemetry to capture more detailed data and corroborate our initial observations.

The recurrence on September 10 provided the additional data needed to confirm the root cause, and a fix is now being implemented. In the meantime, we are actively monitoring for gateway timeouts and restarting the application as needed to maintain service stability until the permanent fix is deployed.

We will continue to provide updates as progress is made.
