A customer reported to us that many of his users have been getting the "Our systems have detected unusual traffic from your computer network" message from Google since last week. Apparently, this is only happening for IPv6, which makes me suspect that there is some kind of glitch with Google's technique for detecting what they believe is automated traffic.
I presume it's per IP block, so it's not at all surprising that it "happens only for IPv6". So are you sure that there's no automated traffic happening? (Netflow should/might tell you that.)
Kind regards Philipp Kern
