2024-February-20 Resolved Service Incident
Incident Report for Sauce Labs


Monday February 19th 2024, 11:20 UTC - Tuesday February 20th, 10:15 UTC

What happened:

Some Emulator and Simulator sessions with typically long startup times were unable to start.

Why it happened:

A service was updated to improve its performance.  This service handles waiting additional time for a VM to become available.  Its internal logic was modified to process a single wait request, but sometimes additional wait requests are necessary.

How we fixed it:

The deployment was reverted.

What we are doing to prevent it from happening again:

We are investigating simulating slower startup times to ensure we can effectively identify similar regressions in the future.
