[JL] Once the issue was escalated to me (thank you), it was fixed very quickly. ;-) > [SM] Since I have your attention, if I try comcast's bespoke networkQuality > server (from your L4S tests)...I saw ECT(1) marking on my egressing packets, > but none on the ingressing packets... that does not seem to be in line with > the L4S RFCs (giving another example why RFC text alone is not sufficient for > much). [JL] That is far from a production server and we've been making config changes to that box all last week as we prepare for more testing - I would not trust any recent results. But in any case, if you are not seeing ECN marks on packets coming back to you, and you are off-net, then something on the path back to you is bleaching. Feel free to send me a traceroute privately and we can continue to discuss it.
