I believe, Perfsonar also uses DNS LOC records.

A dedicated attacker can easily glean from past social media where our sites 
are and that we are partnered with Level(3).

As Steve notes, knocking down the precision may be the better approach here.

    I suspect researchers may as well. IMO, the security list is probably not 
the best place to ask if they’re used.
    
    The LOC below record lists 10,000 meters as its horizontal precision, 
however the coordinates' precision is about 100 meters.
    
    IMO, leave them, but knock the precision of the lat/long down to .01 
rather than .001.
