I discovered this about a year ago. I’m in Denver and Comcast was throttling MSFS pretty severely. How do I know? I called them and made a complaint (after the usual round-and-round to get to a live person). The service rep I spoke with denied that they do that but within a couple of hours, throttling seemed to be lifted. This lasted for about 3 months and then it started happening again. This time I loaded NordVPN and that solved the issue immediately. This issue becomes very clear whenever i download new content within the sim. Without the VPN, content downloads at 0.7 to 2 MB/s. With the VPN, I get expected download speeds often in excess of 100MB/s. I don’t know what Comcast’s problem is or why they’d deny the throttling (but then immedaitely, albeit temporarily, fix it). But it seems to be a real thing.
