Report for Sauce Labs
Postmortem
Dates:
Thursday February 29th 2024, 16:25 UTC - Friday March 1st, 00:15 UTC
What happened:
iOS Simulators in our OS-West-1 data center intermittently experienced longer startup times and in some cases failed to acquire a session, resulting in test failure.
Why it happened:
An increase in utilization throughout the Mac Cloud created additional pressure and lack of availability for some images, which resulted in higher-than-normal startup times. In some cases, the startup times were high enough to cause test failure due to abandonment of the session.
How we fixed it:
Burst capacity was leveraged to provide some relief. Later, utilization decreased to normal levels.
What we are doing to prevent it from happening again:
We are working to both increase capacity and decrease startup times for iOS Simulators.
Resolved
After taking remedial action error rates in Desktop and Virtual Device tests are back to normal levels. This incident is resolved
Update
We are currently seeing elevated error rates in Desktop and Virtual device tests in the US-West-1 datacenter. We are still investigating.
