Incident
Report for Sauce Labs
Postmortem
Dates:
Tuesday, March 24th 2026, 09:32 UTC – 15:13 UTC
What happened:
Network calls failed on iOS devices during Real Device Cloud sessions where network capture was enabled. Approximately 12-13% of iOS sessions were affected. Android was not impacted.
Why it happened:
A deployment introduced a DNS resolution change that was incompatible with the iOS platform, causing network capture to break.
How we fixed it:
Rolled back the deployment to restore service.
What we are doing to prevent it from happening again:
Adding synthetic tests to catch network capture regressions before production, and implementing monitoring alerts for faster detection after deployments.
Resolved
Between 09:32 and 15:13 UTC, we identified a technical issue affecting iOS tests when running with network capture enabled. We've resolved the underlying cause and tests are working as expected. All services are fully operational.
