Amazon links are failing to onebox with a 503
error. This was reported on a customer’s site. I’m able to reproduce the issue on Meta and on our sandbox site: Amazon onebox tests - Demo. I’ve tested on the sandbox site just in case false positive results are returned on Meta due to cached oneboxes. The link below should show the issue though:

On my local development site, the above link is converted to a onebox without any issue. Possibly the problem on production sites is related to the onebox user agent. I don’t think that user agent gets set in development mode.
