From twelve99.net:


If you’re interested in our IP city prefixes, we have a lookup table on our
website: https://www.arelion.com/our-network/bgp-routing/bgp-communities
Scroll down to “Origin + Communities” and expand that section. You can see
that sea-b1 (your hop 8) is not in Brussels, but is our router in Seattle.



My guess would be that the hostname “us-was” for Liberty Global (aorta.net)
stands for U.S.A. and Washington D.C, not Warsaw. They’re probably using
ICMP tunneling for their MPLS backbone, that’s why the ping times are weird
for you.


Cheers!
