Since this morning around 9h the connection with DPA was intermittently down. These were the errors you could see when trying to book shipments:

Bad Request: An internal server error occurred, - I/O error: wsshipper.dpd.nl:443 failed to respond; nested exception is org.apache.http.NoHttpResponseException: wsshipper.dpd.nl:443 failed to respondShipment submit failure: Shipment booking failed.

The issue was located on the carrier's side and was solved by them around 12h.
