Reproducible problem with Rubygems when using FREEDOME
# This minimal script seems to reproduce the issue with Rubygems
#
# It seems Ruby DNS resolver does something odd, as when FREEDOME is on, this
# fails with a SocketError, and when FreeDOME is off it fails with a
# Resolv::ResolvError.
#
# This code is built based on Rubygems source code:
# https://github.com/rubygems/rubygems/blob/v2.3.0/lib/rubygems/remote_fetcher.rb#L92-L93
#
# That code is in the backtrace of `gem install --backtrace jekyll` when this error happens.

4. Choose "Local File" and point it to this file
