I'm new to DO, and when I deployed my first droplet, I was able to deploy to the San Francisco DC, and the Amsterdam DC showed it wasn't available due to demand... Now I can't even see San Francisco or Amsterdam as an option for Data Centers. Is this because they aren't available due to demand and they'll be back soon? Or some other reason? My preference would be to have them greyed out, with an estimated date of when they should be available. That way I'd at least be able to make appropriate plans.
