Peer Routing Issues Between Xfinity and Microsoft 365 / Azure endpoints?

I'm experiencing intermittent TCP connection resets to Microsoft 365 / Azure endpoints from Xfinity access points in vicinity of Harrisburg, PA.    These intermittent connection resets go away when I use a VPN to a different city.    Other than these occasional resets to Microsoft 365 / Azure endpoints, my Internet service works well. 

Are there any known routing or peering issues between Xfinity and Microsoft cloud services (Microsoft 365 / Azure) in the Harrisburg, PA area?
