I'd like to highlight this is for testing purposes only and should have a short
life. We just wanted to make sure the "redirect penalty" that we experience with
our prod redirects is also reflected in our testing so we can get more accurate
results.

Sinny,

One thing we might want to do is use https for the cloudfron URLs like we are for
the prod redirects. Otherwise LGTM.

Ah yes, nice catch. Updated patch is available in the attachment.
This is the sad part part of doing copy paste :/
