Wow, moving an IP address between two #Azure subscriptions takes over an hour (and counting) and it has to be disconnected from a VM while doing so. How on Earth do you design infrastructure where an operation that should be updating one table in a database takes so long? Even manual telephone exchanges could do the equivalent operation faster.
@david_chisnall it's been a while but my impression of azure is it's meant for forklifting servers into the cloud and not dynamic usage. I suspect a lot of operations are shipped as an MVP where the API call creates a ticket and some operator does the work.
