UiPath Status

Postmortem: ## Customer Impact

Between January 16 and January 20, 2026, customers in the Europe region experienced sporadic, intermittent errors in the Document Understanding Classification, Extraction, and Validation services. These errors led to failed requests and temporary disruptions in document processing workflows. The issue worsened on January 19 and was completely resolved by 17:43 UTC on January 20.

Root Cause

The root cause was identified as certain uploaded files containing unusual characters in their filenames, which triggered repeated crashes in a key service component.

Detection

On January 19, the issue was detected by our automated monitoring and later confirmed by customer reports. Previously, the issue reproduced with a lower frequency and was below alerting threshold.

Response

Our engineering team started investigating on January 19, but initially the extent of the impact was not apparent. On January 20 at 13:18 UTC, the UiPath status page was updated and we immediately started mitigating the problem. While a fix was being developed and deployed, we took steps to mitigate the issue. By 13:25 UTC, we had partially mitigated the issue and it was completely resolved by 17:43 UTC.

Follow-Up

To prevent similar issues, we are implementing improved input validation, strengthening error handling, enhancing monitoring for earlier detection, and refining our deployment and testing processes to address additional edge cases.
