Architecture Diagram

Do you have an architecture diagram which show the various systems feeding into your API? I occasionally come across references to things like TrackerNet, iBus, DLR Daisy etc and am curious as to how they all fit together.

I know the point of the unified API is that I shouldn’t have to care about these systems, but it’d be useful in trying to debug dodgy data coming back, or work out why the API is showing something different to dot matrix display boards at a stop. In the past I’ve tried to work out data flows by asking various customer service accounts on twitter, but as the people operating those aren’t usually particularly technical, I end up with Thames Clippers blaming iBus and TFL Buses blaming Thames Clippers.
