As I wrote in my comment on a post by Maxwell Graf (https://feedback.secondlife.com/feature-requests/p/change-the-mapssecondlifecom-search-to-require-only-a-region-name-not-a-full-slu), it seems that the SL Web map now finally lets us specify a region by name in the maps URL without requiring us to also enter a set of coordinates.
It's only a partial fix, however, because it will still be unable to find that region if you don't include a trailing slash. Compare https://maps.secondlife.com/secondlife/Bryggen to https://maps.secondlife.com/secondlife/Bryggen/
It should ideally be able to locate the region with or without the slash there.
