During this planned T-Mobile maintenance window, file transfers — including CDRs — will be delayed and processed once maintenance is complete. APIs may also be affected, so 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.
