 very least, we want to collect information that can help Tor Browser make
 informed circumvention decisions.
 - I like the simplicity of binary true/false values for each of these
 because it will help people make decisions on what to use. But I'm worried
 it will be difficult for us actually decide which it should be, and we
 should be clear about how we make the decision to finally say reachability
 is `false`. Is it when 50% of bridgedb bridges are unreachable? For
 unpublished bridges is it when we do our own ad-hoc tests on some bridges
 we set up like in #29279?
 - Can we add one for downloading Tor Browser? Might be nice to see which
 places need GetTor. If we want to really expand our understanding of
 GetTor we could include each of the link providers and our distribution
 methods for the links.

 > * Referring to bridges as "published" and "unpublished" is somewhat
 misleading because bridges are never public. Any ideas for better terms?
 Perhaps "bridge_obfs4" vs "unlisted_obfs4"? or listed vs. unlisted?
 >
 > * Censorship isn't necessarily uniform across a country and may differ
 from AS to AS: `location_id` is either a country code (e.g., cn) or an ASN
 (e.g., 1234). An ASN has preference over a country code.
 Nice!
