Not been having trouble myself.  I have had connection reset issues
before, but usually that is indicative of my ISP having some sort of
trouble.  I haven't had such issues, though, since I've been reaching
Google over IPv6.

Google doesn't necessary limit connections; they use some heuristic to
try to filter out automated queries, particularly when a large number of
them appear to be repeated.  I can't describe the heuristic exactly,
obviously, but I haven't seen it tripped myself in quite some time.
