Seeing issues with Alter.net in Seattle to a Qwest DSL customer in
Portland (and looks like a possible routing loop as well) from
Calgary:
traceroute 63.227.218.201
Type escape sequence to abort.

Seeing pings jump from 0 ms to 200+ ms at hop 4 (which also appears as
hop 5), and is definitely *not* explained by geographical distance.
Traceroute from my Toronto POP are fine:
