Large RTT or Why doesn't my ping traffic get discarded?

Wed Dec 21 17:10:13 UTC 2022

Here's a question I haven't bothered to ask until now. Can someone please
help me understand why I receive a ping reply after almost 5 seconds? As I
understand it, buffers in SP gear are generally 100ms. According to my math
this round trip should have been discarded around the 1 second mark, even
in a long path. Maybe I should buy a lottery ticket. I don't get it. What
is happening here?
