### 2026-11-06 19:56 UTC: postmortem
### \*\*Dates:\*\*
Tuesday, October 13th 2026, 06:56 UTC - 20:22 UTC
### \*\*What happened:\*\*
Sauce Labs UI experienced increased response times and intermittent 504 Gateway Timeout errors in the EU-Central-1 and Asia-South-2 data centers.
### \*\*Why it happened:\*\*
A routine network configuration deployment by a third-party provider led to regional network congestion, causing a portion of the traffic to spill over into smaller routing paths and resulting in intermittent TCP connection failures.
### \*\*How we fixed it:\*\*
Once network connectivity was restored, we verified the recovery of affected service.
### \*\*What we are doing to prevent it from happening again:\*\*
\* Further strengthen network redundancy to improve resilience against third-party provider failures and reduce the risk of connectivity disruptions.
\* Enhance monitoring and alerting to improve visibility into network connectivity issues.
