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):
