4. resolved Apr 10, 2026, 02:31 AM UTC

   We have successfully resolved the networking issues in the US-IAD (Washington) data center. The cause was identified as a specific compute host that generated abnormal network traffic upon being powered on, which impacted the local management network and a subset of customer connectivity. Our engineering team has isolated the hardware responsible, and network stability was restored immediately. All management services are fully operational, and the backlog of pending host jobs has been completely processed. We will continue to monitor the region to ensure ongoing stability.

5. postmortem Apr 13, 2026, 04:51 AM UTC

   Starting around 22:55 UTC on April 9, 2026, customers were unable to access services hosted in the US-IAD \(Washington\) data center \(DC\). The investigation revealed that the issue was caused by network connectivity issues, which would have resulted in connection timeouts and/or errors for services deployed in this data center. Analysis confirmed that the disruption was triggered by a single compute host that was incorrectly configured and generated abnormal network traffic upon being powered on. To mitigate the impact, we have isolated the host, and the network stability was restored following this action. The impact was mitigated at 02:01 UTC on April 10, 2026. All management services are fully operational, and the backlog of pending host jobs has been completely processed. We will continue to investigate the root cause and will take appropriate preventive measures. We apologize for the impact and thank you for your patience and continued support. If you have further questions, please contact us at 855-454-6633 \(\+1-609-380-7100 Intl.\), or send an email to [[email protected]](mailto:[email protected]) for assistance.
