Comment (by adrelanos):

 Failing:

 {{{
 curl --tlsv1.2
 https://www.torproject.org/projects/torbrowser/RecommendedTBBVersions
 }}}

 > `curl: (35) error:14077102:SSL
 routines:SSL23_GET_SERVER_HELLO:unsupported protocol`

 ----

 Working, but low TLS version:

 {{{
 curl --tlsv1.0
 https://www.torproject.org/projects/torbrowser/RecommendedTBBVersion
 }}}

 {{{--tlsv1.2}}} was working previously. The TLS downgrade was done around
 26 Feb 2018. So this is a regression.
