2020-August-30 Service Incident
Incident Report for Sauce Labs US West Data Center


Sunday August 30 05:00 PDT to Sunday August 30 10:00 PDT

What happened?

Some Sauce Labs customers experienced intermittent connectivity issues.

Why it happened?

CenturyLink, a global Internet backbone network, experienced a network outage that affected the Internet globally, particularly in Europe.

How we fixed it?

Internet Service Providers began disconnecting from CenturyLink while they worked on resolving their outage. As CenturyLink’s outage began to resolve, we started recovering Real Devices that did not recover automatically, and restarted some services.

What we are doing to prevent it from happening again?

We’re adding additional monitoring of external endpoints to provide better insight into issues experienced on the Internet and enable more rapid response.
