Where are the healthy ping times you mentioned?
Pinging from hop 19 to 20 took 583 ms. The traceroute
showed that it took 278 ms to get to hop 19 and 861 ms
to get to hop 20. That's a difference of exactly 583
ms. Seems like the latency is between 19 and 20... I
don't see anything weird about it though.
