2023-October-26 Service Incident
Incident Report for Sauce Labs


Thursday October 26th 2023, 17:03 - 17:30 UTC

What happened:

For the duration of the incident, customers could not upload new files or list files/groups through the Web UI. Some users received an HTTP error code of 429 due to them being rate-limited. 

Why it happened:

Customers began to have issues uploading assets to our storage service due to a high number of concurrent uploads. This spike in upload requests caused a delay in acquiring a backend connection for the storage service. 

How we fixed it:

We recycled the storage service pods, which cleared the connectivity issue with our backend service. 

What we are doing to prevent it from happening again:

We are looking at the following areas:

  • Determining how better to handle periods of increased load for our storage service.
  • Refining our alerting for our storage service to detect performance issues customers may experience when interacting with it.
