Short answer: http://download.geofabrik.de/europe/faroe-islands-latest.osm.pbf

Longer answer: The http://planet.osm.org/ page has a link to “extracts and mirrors”. That has a link to a couple of major providers of extracts, and a list of lots more in the wiki. Various file formats are available; see each site for details (e.g. http://download.geofabrik.de/europe/faroe-islands.html for Geofabrik’s options for the Faroe Islands).
