The Wireless team will be performing a UDSF (Unified Data Storage Function) software version rollback across all three sites (Chicago, Ashburn, and Sydney). This is a precautionary alignment to a Mavenir-supported version. The UDSF pods will restart during the maintenance window. No customer impact is expected. The maintenance is not expected to last more than 2 hours.
