There's little service yet over Greenland, either - about on par with Alaska at present. The current northernmost orbits peter out at about 54~55 degrees north.
That said, there are ground stations in Ketchikan, Fairbanks, Nome and Kuparuk in Alaska, and none yet in Greenland. Nominally, given the ground stations, service should be marginally better in several of the Alaskan cruise ports than anywhere in Greenland, so no excuse for poor service on that count.
