I have been using Speedtest by Ookla on all my devices for several years. I noticed a new icon at the bottom center labeled “Status”. Selecting this provides a LOT of information about various ISPs, web hosting, and apps displaying the number of user reported problems during the last 24 hours. Currently it does not have MSFS on the list of apps. However there are a few apps that MSFS connects to or temporarily uses like Xbox Live (?), Steam, Microsoft Store, and Microsoft Azure. It seems to have most ISPs we use for MSFS. It does not do any real-time monitoring or speed test analysis. All of the data and analysis is User Reported Problems only. The graphs show the # of problems, not network speeds.
I have only looked at USA data although it is possible to select other countries. I think adding MSFS would be very helpful as another tool in our toolbox complimenting the detailed services status page already available.
