We are currently observing an elevated error rate on USPS's Shipment API, which typically affects Rating requests. Shippo's automatic fallback is handling affected requests, so rate quotes and label generation are not impacted. We have reached out to USPS and are actively monitoring the situation. We will provide a further update as soon as we receive one from the carrier.
