This smells like a network issue, not an abuse issue.  Not enough
information was provided on-list, but if you send a traceroute to
noc at google.com they should be able to help you out.

The comment about http://ipv4.google.com/sorry/ is false -- that page will
give you a cookie if you prove you're not a bot, but HTTP cookies can't
help with DNS.  There's no need to memorize that URL... browsers will
automatically 302 there if it will help.
