    \$\begingroup\$ Instead of true and false, I recommend allowing any of our defaults for truthy and falsiness. Also, by internet, do you mean the network outside your local network? Do programs still have to work if say google is down or any other large site? \$\endgroup\$ Commented Jan 13, 2017 at 13:34

    \$\begingroup\$ The very machine I'm typing this at, is technically a part of the "Internet", as it can be accessed from the outside (via NAT and port forwarding). So, if you think of it, the "internet detection" script can probably be reduced to "true" :) \$\endgroup\$ Commented Jan 13, 2017 at 19:55
