Microsoft has acknowledged a disruption affecting Windows Server Update Services (WSUS), preventing organizations from syncing with Microsoft Update and deploying the latest Windows updates. Reports indicate that synchronization has been compromised since last night, with error messages such as "A connection attempt failed" and ".NET errors indicating that 'The operation has timed out.'" Some administrators noted a brief resumption of synchronization around 12:30 am ET, but it was short-lived. Microsoft attributed the issue to a "problematic update revision in the storage layer," which affects devices trying to sync updates via WSUS. There are currently no workarounds available, and Microsoft is working on a resolution.
