Thanks for following up! I eventually got it working - I'd followed the example too closely and had a rogue `us-west-002` left in the config which broke things because I'm apparently on `us-west-000`. But I'll drop an email anyway because I can't see an easy way to see what region you're in other than visually parsing the endpoint URL.
