Incident 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.
