Who knows... Hard to know if I'm taking a different network path or just going through the same routers but bypassing whatever is blocking the packets.
I should probably clarify that I'm not having slowdowns Cys -> Den. I'm having complete and total loss of packets for that one stream/type of traffic.
I went so far as to even randomize source/dest ports on each end in case it was some sort of misguided filtering (ie: port 12345 -> 54321 instead of 12345 -> 12345).
I have working tunnels on CL/Lumen's own network from Cys to multiple endpoints in Boi, so I know its not something on our side in Cys.

I know that many things will operate better in IPv6 land vs IPv4 land as in IPv4 land there’s a lot of port-based filtering that happens in networks which isn’t the same in IPv6-land. Super glad to hear that IPv6 saved the day for you! - Jared
