Is Sauce Labs down?

We are experiencing an issue where the US-EAST data center is currently unavailable. We are investigating.

We are continuing to investigate this issue.

We have identified the root cause and are working on implementing a fix.

Access has been restored to the US-EAST data center. We are monitoring.

After taking remedial action, access to the US-EAST data center is fully restored. This incident is resolved.

Between May 13th 18:47 UTC and May 15th 9:23 UTC, we experienced test details not appearing in the dashboard of the US-East Data Center. This issue has been resolved. All services are fully operational.

### **Dates:** Wednesday, May 13th 2026, 18:47 UTC - Friday, May 15th 2026, 09:23 UTC. ### **What happened:** Customers were unable to access test run summaries for Real Device Cloud \(RDC\) jobs because events stopped publishing to the jobs Kafka topic in US-EAST. ### **Why it happened:** An authentication key used by the message producer unexpectedly lost its permissions during an account cleanup. ### **How we fixed it:** Manually restored the required permissions to re-establish the connection and resume service. ### **What we are doing to prevent it from happening again:** Migrating to a permanent service account, implementing a Dead Letter Queue \(DLQ\) for the jobs Kafka topic, and replaying the missing events to restore customer data.

Between April 23rd 22:44 and April 24th 15:25 UTC, there was a technical issue that affected video recordings for tests running on macOS 15 and iOS within our EU and US-West Data Center. We identified the issue and deployed a fix. All systems are now fully operational.

### **Dates:** Thursday, April 23rd 2026, 22:43 UTC - Friday, April 24th 2026, 15:29 UTC ### **What happened:** Video assets were missing for virtual iOS simulator tests on ARM and macOS ARM desktop tests in the US-West and EU data centers. ### **Why it happened:** A product defect was introduced resulting in a screen capture failure. ### **How we fixed it:** We performed a rollback to a stable version. ### **What we are doing to prevent it from happening again:** We are improving monitoring & alerting to enhance our post deployment validation.

Between 02:00 and 11:15 CEST, live and automated tests on iOS 17.0 simulators were failing to start in the EU and US-West Data Center. We executed a deployment rollback, which restored services. All systems are now fully operational.

### **Dates:** Thursday, April 16th 2026, 00:00 UTC – 09:15 UTC ### **What happened:** Live and automated tests on iOS 17.0 simulators failed to start in both the EU and US-West data centers. Customers running tests on iOS 17.0 Intel-based simulators were unable to execute their tests for approximately 9 hours. ### **Why it happened:** A deployment introduced an incompatibility affecting iOS 17.0 on Intel-based infrastructure. The issue was not caught prior to release due to insufficient post-deployment test coverage for that specific simulator configuration. ### **How we fixed it:** We performed a rollback to the previous deployment, which restored full iOS 17.0 simulator functionality. ### **What we are doing to prevent it from happening again:** We are reviving and expanding automated post-deployment tests to cover a broader range of simulator configurations, including legacy Intel-based iOS versions, to catch incompatibilities before they reach production.

We are currently investigating reports of test failures affecting users running tests using SauceCtl in our US-West-1 and EU-Central-1 Data Center. We are investigating.

We have identified the root cause and have deployed a fix for this issue. All services are fully operational.

### **Dates:** Monday April 7th 2026, ~11:00 – 15:55 UTC ### **What happened:** Some customers experienced 503 errors when running tests via saucectl. The test-composer service was intermittently unavailable, preventing framework-based test execution. ### **Why it happened:** A stale Docker image was deployed to the test-composer service due to a packaging issue that arose during an internal container registry migration. This caused service pods to crash. ### **How we fixed it:** We identified the stale image and redeployed the correct version, restoring the service. ### **What we are doing to prevent it from happening again:** We are hardening our image deployment pipeline and adding validation checks to ensure container registry migrations do not result in stale or incorrect images being deployed to production.
