Emerging Service Issue - GPU Deployment

Summary

Emerging Service Issue - GPU Deployment

On May 19, 2026, at 18:26 UTC, we identified an issue impacting the creation and re-provisioning of Linode instances using any of the four RTX PRO 6000 Blackwell \(g3-gpu-rtxpro6000-blackwell\) plans, resulting in API errors. These failures caused a denial of service for customers attempting to deploy g3-gpu-rtxpro6000-blackwell instances via the Cloud Manager or API. After the initial investigation SMEs determined that the cause of the issue was a logic error within a recent APIv4 update. Specifically, a validation check intended only for RDMA-enabled networking was incorrectly applied to standard Blackwell GPU plans. This caused the API to reject creation requests that did not meet specific RDMA configurations, even when those configurations were not required for the selected plan. With the issue identified, our engineering team developed and tested a hotfix to correct the plan-validation logic. Deployment of the fix began shortly after, and broader customer impact was mitigated as of 21:36 UTC on May 19, 2026, following successful verification in all regions. This summary provides an overview of our current understanding of the incident given the information available. Our investigation is ongoing, and we are currently reviewing our automated testing to prevent similar recurrences.
