I have had the G-bot visiting my sites hard for the past month, but since the beginning of this week I have had the a Googlebot from one particular IP pounding one of my sites to the tune of as many as 5,000 pages per hour. The fact that it is coming from just one IP address makes me think that this is not supposed to be happening (I have verified it is one of G's IP's).
Is anybody else seeing this?
