Engine scaling issues in Dremio Cloud (US)

We are investigating an issue preventing some engines from starting on Dremio Cloud (US). Users with classic engines may be unable to scale up or start new engines. Our team has identified a potential cause and is actively working on a fix. We will provide an update as more information becomes available.

A fix has been applied for the engine scaling issue on Dremio Cloud (US). Engines should now be able to start and scale normally. Our team is monitoring to confirm full recovery across all affected environments.

This incident has been resolved. Earlier today, an infrastructure issue on Dremio Cloud (US) prevented some engines from starting or scaling up. Our team identified the cause, deployed a fix, and confirmed that engine operations have returned to normal. We appreciate your patience.

On August 26, 2026, between approximately 12:30 PM and 2:45 PM PDT, some users on Dremio Cloud (US) were unable to start or scale up engines. The issue was caused by an infrastructure artifact required for engine provisioning being inadvertently removed during a compliance-related infrastructure change. Engines that were already running were not affected.

Our team identified the root cause, restored the affected component across all US regions, and confirmed that engine operations returned to normal. Beyond this fix, we are conducting a broader review of our infrastructure maintenance workflows to strengthen production dependency checks, and implementing monitoring for critical provisioning components to catch similar issues sooner. We recognize the impact this had on your operations and apologize for the disruption. Thank you for your patience as we worked to resolve it.
