Yep! A known G intrusion attack. Got the same on my server today, worst I've seen so far.
We THINK that G thinks it should see how you site works when presented with garbage. If G got on with sorting out their own house instead of trying it on in ours they may begin to get a better reputation. Although I doubt it.
Since the attacks come from real bot IPs with real bot UAs etc there isn't much can be done about it other than block using 404 or, in my case, a 403 or 405 because an html extension is an illegal access attempt on the site.
I've been contemplating, this past couple of hours, removing G's access entirely from at least one of my sites. It's no business of theirs and their actions and instrusions are getting worse.
