This page is about in interesting problem that was reported to us, by a customer, in December 2021. We have written this up so that this page can be found if other people are seeing a similar problem.
We've masked the IP we're pinging in this page as it doesn't matter what IP you ping - in our tests though we were mostly pinging the IP of our LNS, as that is the 'next hop' on the customer's route to the internet.
=TL;DR=
For some reason, TalkTalk's kit is reading IP DSCP marks from IPv4
1408 bytes from x.x.x.x: icmp_seq=986 ttl=63 time='''19084.589 ms'''
