Another anecdote: I manage a a couple of hundred VMs, databases, storage accounts, event hubs, Azure Web Apps and much more. Errors in the UI is pretty much a non-issue to me. I have multiple user accounts and manage multiple subscriptions and sometimes switching accounts gives me an error and I have to logout and back in. A bit annoying but hardly something which would make me switch.

I do suspect that their portal will not work well if the connection between you and their data center is shaky though.
