That's embarrassing. Thanks for opening my eyes.

Sorry for wasting everyone's time.

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
