During this planned T-Mobile maintenance window, two brief service interruptions of approximately five minutes each are expected — one near the start and one near the end of the window. API and provisioning transactions will be unavailable during those short interruptions and available for the remainder of the window. Partners are advised to pause bulk provisioning and avoid submitting transactions where possible during the maintenance period, as intermittent failures and delays may occur. This may affect porting, provisioning, and other number-specific updates. Any changes to the maintenance window will be communicated here, and further updates will be provided as needed.
