Does Google treat .af (Afghanistan) as an international domain though? Not sure if they take the TLD into account much anymore when determining the regional focus of a page, I know some TLDs like .io and .ai are treated as non-regional, not sure about .af though. Problably not a large problem though, just haven't seen many .af product sites so far (really great, short domain name otherwise).

Good question, no idea. The main domain is primo.so, so I think at the very least that should be safe.
