The issue has been resolved and we're not routing through Shippo anymore. The cause of the outage was FedEx revoked our credentials as part of a maintenance. The revokation was unintentional but it was difficult to get it restored. The FedEx team has restored our credentials. We will be working more closely with the FedEx team going forward.

Update
The issue is that FedEx seems to have revoked or updated our API key during their maintenance window, we've been trying to speak to FedEx web services technical support to resolve but without success so far as they are closed on Sundays.
