UiPath Status

Postmortem: ## Customer Impact

Between February 4, 11:34 UTC and February 4, 03:00 UTC, UiPath customers located in the UK region, as well as customers connecting via VPN endpoints with UK-based IP addresses, experienced service disruptions affecting Orchestrator and related services.

During this period, users encountered multiple errors, including failed authentication, asset retrieval failures, and general unavailability of core automation services, resulting in degraded platform access.

Root Cause

The outage happened because our cloud provider changed their API Gateway in the UK. This update added a system that limits how much traffic goes through the system. This caused UiPath traffic to slow down and cause problems with service.

Detection

Automated monitoring quickly detected the issue, alerting Engineering staff to elevated rates of HTTP 503 errors in the UK region.

Response

To mitigate the impact, we updated our network configuration, and re-routed all UK traffic to our European API Gateway, which had not yet received the new update. This ensured that customer traffic was no longer subject to throttling behavior and restored service availability.

Follow-up and preventive actions

We are working with our cloud provider to learn more about the new throttling feature.

To stop similar events from happening again, we have done the following.

• Requested our cloud provider to pause the rollout of the new feature and disable the throttling functionality in regions where it has already been deployed.
• Moved all production API Gateways into the cloud provider's delayed rollout group. We also assigned alpha API Gateways to the early rollout group. This lets us find and fix problems earlier in the release cycle.

Resolved: The incident has been resolved, and our monitoring systems confirm that services are operating normally. Initial investigation indicates that users in the United Kingdom were most affected, followed by South Africa. The primary impacted service was Orchestrator

Monitoring: We’re seeing a reduction in errors. We continue to closely monitor system performance through our monitoring platform and will provide another update shortly

Investigating: Multiple services are experiencing intermittent availability issues across multiple regions, resulting in occasional 503 errors for some requests

Postmortem: ## Customer Impact

Between 09:41 UTC and 13:24 UTC, customers using IXP in the U.S. experienced generally poor performance in the form of slow API requests.

In addition, these specific actions had increased error rates:

• Consuming stream
• Uploading documents

For a small number of specific clients, streams were unable to be consumed entirely during this time.

Root Cause

An IXP database migration took place in the U.S. region at 09:41 UTC on February 3, 2026.

This migration changed the underlying database queries used by several of our API routes. One of these database queries was poorly optimized, leading to bad performance when executed against the high volume of data present in the U.S. region. This database query was used by the streams and document upload routes.

Detection

Our engineering team was closely monitoring the migration, and observed an increase in stream response times. In addition, automated alerts picked up on the increased error rates and automatically alerted us while an investigation was underway.

Response

The team worked to find and fix the problem with the database query. At 13:04 UTC, a hotfix was deployed. By 13:24 UTC, API response times and IXP performance had returned to normal.

Follow-Up

We recognize how disruptive this incident was for our customers, especially those relying on timely document processing and stream analytics. The IXP team will ensure that in future, similar migrations:

• Have better performance testing
• Have faster rollback capabilities

Resolved: The incident has been resolved and system performance has returned to normal. A postmortem will be shared soon with additional details.

Monitoring: The fix has been applied and we are seeing improvements in system performance through our monitoring systems. We will continue to closely monitor performance for some time before marking the incident as resolved.

Identified: Our hotfix deployment is currently in progress. We will provide an update once the deployment is complete and we begin monitoring system behavior to ensure performance is fully restored

Identified: Our engineering team has identified a fix and is actively working on rolling it out to restore normal performance.

Investigating: We have identified the issue our engineering team is actively working on a fix to restore normal performance. Our investigation also indicates that the issue is affecting overall IXP performance in the US region, and is not limited to Streams

Investigating: We are currently investigating an issue causing performance degradation and increased latency for Streams in the US region. Some customers may experience slow response times (exceeding 5 minutes) and request timeouts when calling Streams

Resolved: The issue has been mitigated, but customers may continue to experience intermittent ingestion delays until our cloud service provider provides a full resolution.

Monitoring: This issue has been mitigated but the team is still investigating with underlying cloud service provider and will look to provide more information once available.

Identified: Our investigation shows that the issue is related to our cloud service provider. We have escalated this with them and are actively monitoring progress, the resolution may take some time. We will share updates as soon as we have more definitive information

Investigating: We are investigating an issue causing delayed ingestion of Queue Item data in Insights for customers in the US region.

Resolved: The incident has been resolved, and our monitoring systems confirm that marketplace website operating normally.

Monitoring: Marketplace team has applied the fix and we are currently monitoring.

Investigating: We are currently investigating an issue causing degraded performance and timeouts on the marketplace website.
