I have also been wondering about this because I have also noticed that I seem to get online interruptions during weekends and Friday evenings. Microsoft do apparently monitor online services and report that services are “operational”. However, it is not really clear what that really means and it might be more useful and transparent if MS could tell us what their standard of service level is and perhaps give us some actual metrics such as per cent of service requests met. Not sure if MSFS is using dedicated servers or whether it is just using the MS XBox gaming servers. Either way they might be able to provide a little more information on service levels. -,
