2019-December-12 Service Incident
Incident Report for Sauce Labs US West Data Center


December 12th, 10:40 - 11:10 PDT

What happened:

Some customers experienced high wait times running tests in our PC, Mac, &/or Android clouds in our US-West datacenter.

Why it happened:

A failure within our DNS infrastructure resulted in a loss of connectivity from an availability zone to our control plane for 20 to 40 minutes at a time.

How we fixed it:

We’ve modified the configuration of our DNS servers to respond to the error condition and recover immediately.

What we are doing to prevent it from happening again:

  • We’ve developed extensive playbooks that will allow us to diagnose and respond more rapidly to an event where our VMs have lost connectivity to our control plane.
  • We’ve deployed new test infrastructure that validates our configuration and gives us rapid feedback to the conditions and quality of our environment
  • We’ve deployed additional logging and monitoring of our Load Balancing and DNS infrastructure.
  • We’ve configured additional network level logging to provide advanced diagnostics and replay of failure scenarios.
