Unable to upload items on Workspace - US

Resolved after 4 hours 23 minutes, affecting Secure Workspace, on May 12, 2026.

postmortem May 21, 2026, 04:25 PM UTC

On Tuesday, May 12, 2026, from approximately 10:12 until 11:43 \(UTC\), some US customers experienced issues while attempting to upload files or process data within the Workspace console. This incident was caused by a networking disruption that affected a backend messaging service, preventing it from properly syncing data. While file downloads remained available, new file uploads and certain background tasks were blocked. To resolve this issue, we temporarily paused new network traffic and restored the messaging service. The Workspace console returned to normal performance by 11:43 \(UTC\). To prevent this type of issue in the future, we are reviewing our messaging service configuration and improving network monitoring to more quickly identify synchronization issues. No data loss occurred as a result of this issue.
