SKY API Documentation Feedback - Response Codes

In using the SKY API I've had a few response codes come across when making API calls:

500 - which is in the documentation, which states I should never receive this, and to report this, but I end up just trying the API calls again and usually am successful.

But these 2 are not in the documentation:

502 - is a Bad Gateway code. While certainly not critical, I was wondering if this could be added to the documentation, with perhaps an explanation from the perspective of the API vs the generic “Bad Gateway” message.

408 - is a Request Timeout, which should be a client side error. I'm not sure why I received this one, but nonetheless, maybe just a mention in the API for completeness, as I jumped over to the documentation first, and then went to Google to find its meaning.

Thanks!
