From what I can tell, Google Cloud Functions is only available in us-central1, as the drop-down for selecting a region only allows me to select us-central1, and when I try writing my own deploy script using something different for the region option like us-east4, the deploy fails. Is this the case? Is there some hidden way to enable creating a cloud function in us-east4 or some other region?
update: the linked question clarifies this for Firebase but I would love to see an official answer for Cloud Functions in general. My guess based on what I've found online is that until Cloud Functions is out of beta, it will only be available in us-central1.
