USPS has scheduled maintenance for its Product Tracking service. During the maintenance window, customers using the USPS Tracking API may experience brief service disruptions affecting subscription requests and Track API calls
These outages will occur on a rolling basis across different parts of the network; therefore, the service disruption duration should only last minutes rather than the entire duration of the maintenance window.
Start Time: Sunday, July 19 at 8:00 PM ET
End Time: Monday, July 20 at 4:00 AM ET
If you have any questions or concerns, please feel free to contact us.
Thank you,
