thanks Andreas,

really appreciate your response 🙂

yes this is the same article i have researched and as we have 2 DC's when running off the secondary (where witness resides) is when the quorum is lost and they are pretty exposed in regards to failback if that DC goes down..

ultimately monitoring will be done to ensure the instance is running from the primary as much as possible, otherwise they are in the situation where the mirrors need to be broken so that those db's that were mirrors can br brought online..
