v-m: Redo Internet/DNS connectivity checks (again) 

Using domain names in the "blackbox" probe makes it difficult to tell
the difference between a complete Internet outage and DNS issues.  I
switched to using these names when I changed how the firewall routed
traffic to the public DNS servers, since those were the IP addresses
I was using to determine if the Internet was "up."  I think it makes
sense, though, to just ping the upstream gateway for that check.  If
EverFast changes their routing or numbering, we'll just have to update
our checks to match.
