  3. identified Nov 25, 2020, 03:18 PM UTC

    Initial investigation indicates that the connectivity error happens because Mastercard’s directory server is not accepting our client certificate for mutual TLS.

Notice that this incident is not affecting transaction processing (acquiring), 3-D Secure version 1 (MPI), nor 3-D Secure version 2 for Visa.
