Is this still happening?

Phil,

The traceroute was done by a coworker in Quebec on April 26, from one of
our corporate offices. His IP address was probably 104.163.180.188 at
the time. He was tracing one of our endpoints in AWS us-west-2; I do not
know which IPs our endpoint had at the time, but one of its current IPs
is 52.89.73.31

This is the trace as he described it:

We expected that trace to go straight East Coast / West Coast, but
instead it went through Europe.

For comparison, this is a trace also by same coworker to
api.postmates.com, which was correctly routed on the shortest
geographical path (more or less):

Hey Florin,

Do you have a traceroute showing the issue? FYI, you can test against
any
of the IPs listed here under US-West-2, they all respond to ICMP
requests.

I've seen a few strange instances where IP addresses in the AWS
us-west-2 region (Oregon) are routed through Europe if you start the
traceroute from some providers in the northern East Coast (Quebec,
New
York). Any idea what's going on? I assume it's temporary.


Can you be a little bit more vague in your problem description?
While
ommitting the source networks from where you tried, you still
included
the destination.  The list expects better.


Sorry. Here's one source: 104.163.180.188
