- postmortem Aug 18, 2025, 04:40 PM UTC
On August 7, 2025, at 17:16 UTC, we received a notification that some customers were unable to open their workspaces. During the incident, customers attempting to open workspaces by the modeling UI may have encountered intermittent errors, hanging, or slowness. Already opened workspaces or workspaces opened by scheduled actions or integration were unaffected. This issue impacted the following regions: * us1: Data Center - US East * us2: Data Center - US West * eu1: Data Center - Netherlands * eu2: Data Center – Germany * eu4: Cloud – Europe * us5: Cloud - US East * ap1: Cloud – Japan * us7: Cloud - US We reviewed the logs and found errors in relation to the Content Delivery Network \(CDN\). Analysis of the errors identified that the issue occurred when a workspace attempted to open but was unable to resolve the client content location. We identified that the CDN had experienced intermittent issues between 17:00–19:00 UTC. When the CDN was functioning without issue, the workspaces opened on retry. A small proportion of workspaces cached the CDN error and required a manual restart to resolve. The restart completed for these workspaces by 19:48 UTC. We have completed a thorough review of the incident. We are currently working with the CDN provider to identify the cause of the issue and preventative measures. We are also implementing a fix to prevent workspaces from caching CDN error messages. This will ensure that workspaces can recover without manual intervention in the future. Additionally, we are refining our alerting and observability capabilities for the CDN service. We apologize for any impact this issue may have had on your business operations. We are continuously strengthening our systems and procedures to help prevent future disruptions to your business.

Thank you for your patience during this situation, and we appreciate your continued trust in Anaplan.
