Was Dunbar the reason for the unusually arduous covid restrictions in Anchorage but basically nowhere else on the road network?

(I visited AK in February, in Fairbanks and elsewhere everything was almost perfectly normal, and there weren't too many restrictions, but in the Municipality of Anchorage, indoor dining had only just reopened recently, and they requested contact tracing phone numbers to sit in the restaurants.

Visiting from the wide-open Florida, Anchorage was behaving like New York City even though there was no issue 30 miles away...)
