The connectivity was pretty terrible in Alaska, at least as of November of last year when I cancelled and returned Starlink.

They have a certain number of near-polar orbit satellites. There's not yet the same level of coverage as inside 57 degrees, but they do have ground stations and offer coverage, though it seems to be of the "just barely" sort. The polar orbits are rapidly filling in, however, so it should get better before too long.
