2022-May-20 Service Incident
Incident Report for Sauce Labs


Wednesday May 20th 2022, 11:50 - 13:15 UTC

What happened:

Sauce Connect tunnels intermittently failed to start in our eu-central-1 data center.

Why it happened:

Unusually high load caused our back-end systems to respond slower than usual.

How we fixed it:

The system restored its normal behavior after the load was decreased.

What we are doing to prevent it from happening again:

  • We are planning to improve our back-end system performance in EU-Central to be able to handle this workload
  • We will introduce stricter rate-limiting rules to ensure that an individual user cannot affect the system performance
