Yeah. But it's not unheard of for the Apple servers to go mental and things grinding to a halt or it not activating etc.
Usually we'll get the GM after the keynote, the public release is usually a couple of days before the new iPhone release. Tonight I usually stay up late trying to get the GM from suspect locations so then I can have iOS 11 before the public onslaught in a few days.
EDIT: They're signing the GM again.
