Centurylink Boise Networking Oddness

Fri Oct 9 23:54:24 UTC 2020

It is a tad bit unusual yes, but not surprising from Boise.  Our connections have to go out to Seattle or other neighboring states before hitting any major IX.

Well, that and basing issues solely on ICMP echos and trace routes can be tricky, given that they are low priority and require hitting the CPU on routers...

Glad the issue seems to be resolved though.
