I'm just a private individual hosting his blog on Azure, and I've had a stellar experience. I made a post about some gripes I had setting up my website, and a person from the developer outreach program reached out to me and put me in touch with the engineering team directly. Turns out my main complaint (lack of support for managed SSL cert for root domains) was already in the pipeline. They even sent a bunch of MS/Azure gear to my doorstep as a thanks for my feedback.
