Comment:

 I think YAML is more suitable for this task. How about the following
 structure?

 {{{
 location_id:                    # Two-letter country code or ASN; in this
 case "cn".
   infrastructure:
     website: false              # Is torproject.org reachable?
     bridgedb_www: false         # Is bridges.torproject.org reachable?
     bridgedb_moat: true         # Is moat's cloud front reachable?
   relays: false                 # Are (a subset of) relays reachable?
   dirauths: false               # Are directory authorities reachable?
   bridges:
     default: false              # Are default bridges reachable?
     published_vanilla: false    # Are vanilla bridges in BridgeDB
 reachable?
     unpublished_vanilla: false  # Are unpublished vanilla bridges
 reachable?
     published_obfs4: false      # Are obfs4 bridges in BridgeDB reachable?
     unpublished_obfs4: true     # Are unpublished obfs4 bridges reachable?
     meek-azure: true            # Does meek over Azure work?
 }}}

 * What other information do we want to capture in this snapshot? At the
 very least, we want to collect information that can help Tor Browser make
 informed circumvention decisions.

 * Referring to bridges as "published" and "unpublished" is somewhat
 misleading because bridges are never public. Any ideas for better terms?

 * 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.

 * We can use the censorship analyser from #30794 to quickly gather this
 information.
