Slow behaviour in Slack
Resolved MinorIncident Report
Summary AI Generated
Slack workflows experienced failures where triggered workflows would not complete due to the first step failing to execute, primarily affecting EU users. The issue was caused by elevated latency in EU backend services, which led to workflow trigger attempts failing for a subset of users. A fix was deployed to address the backend latency issues, and the team monitored the environment until full service recovery was achieved.
Some users are experiencing issues with workflows. Triggered workflows may fail to complete, with the first step not executing. We'll provide another update as soon as possible.
