Unable to Publish Workbooks
Resolved - At approximately 22:38 UTC on September 10, 2024, some Sigma users were unable to publish workbooks and upload CSVs due to a spike in error rates caused by a third-party service network rule. The incident has been resolved by disabling the rule that was triggering the issue and Sigma is actively working with the service to mitigate this in the future.

Users should now be able to publish workbooks and the Sigma app is fully operational. We will perform a root cause analysis (RCA) and publish our findings in a postmortem note to the Sigma Community site in coming days.
