@eskimo - thanks for the reply. Digging into our logs we found there was a change on the preferred methods for uploading the file for notarization. This change started to reflect on 11/7/2020: Then: [2020-10-27 14:32:40 PDT] <main> DBG-X: parameter PreferredTransports = [HTTP, Signiant, Aspera, DAV] Now: [2020-11-09 17:47:03 PST] <main> DBG-X: parameter PreferredTransports = [HTTP, DAV] Why the change? We are not controlling this. Signiant is way faster than DAV. Is there a plan to bring Signiant and Aspera back? FYI - We logged this (FB8893559) Thanks!!!

@eskimo, We have experienced slowliness on ntoarization requests starting on Sunday. We send several requests per day for the last months without any major issues but on these last days response is very slow and we are getting errors returned due to duplicate whereas in the past this was managed differently. Is there any documentation of any changes on the notarization end that we can get? We serve several major apps that are getting impacted by this. We don't have any clue of what is happening as the status shows as available.
