Outage Details
Impact Statement: Starting at 23:54 UTC on 26 September 2025, customers in Switzerland North may experience service unavailability or degraded performances for resources hosted in the region. Virtual Machines may have shutdown to preserve data integrity. Current Status: We were alerted to this issue by our telemetry informing us in a significant drop in traffic. It was discovered that a recent deployment introduced a malformed prefix in one of the certificates used for connection authorization. We have pinpointed the deployment error involving the certificate prefix and are rolling back the faulty deployment to restore normal traffic flow and service availability.We are seeing success and will continue to monitor traffic and service stability to ensure full recovery, at this stage we expect to fully mitigate by 05:30 UTC.
