2020-March-17 Service Incident
Incident Report for Sauce Labs US West Data Center


Tuesday March 17 10:31 AM - 11:06 AM PT

What happened:

Customers using our US-WEST datacenter were unable to load our website, login to our UI, or run tests.

Why it happened:

Our internal service health monitoring mechanisms were set to be too aggressive. This caused user authentication to fail on parts of our system.

How we fixed it:

We have revised our service health monitoring settings to more moderate values.

What we are doing to prevent it from happening again:

We have extended times for our health checks and implemented additional monitoring measures to get notified about potential issues earlier if something similar happens in the future.
