Yes, but speaking as someone who's worked for Brits more than once, including my most recent job, the term 'as at' is not used in the states. We use 'as of' a certain date.
I'm shocked about Juneau. I think if you went up to 10 Americans on the street and asked what the capital of Alaska is you'd only get one or two correct answers
Pretty sure it's because Hawaii and Alaska both are off on their own, many quiz takers start by guessing them first. Also Alaska appears in the 2nd position on a list of states ordered alphabetically.
