we had lots of crawler activity today on a newer site, google hit the site from 3 different ip addresses throughout the day. hoping it's a good sign, never seen them use different ip addresses in the same day before.
I miss the days in which I had time and energy enough to monitor activity to this degree. Lately the only time I pay such close attention to Googlebot activities is with a test case or when something has gone horribly wrong and it reaches my bottom line.
Yea they went berzerk on our big site last thursday and friday. their fast activity notified me so I took a peek to see who was scraping the site... I've never seen Google spider so fast and from so many IP addresses, they were all valid Google ip's but there was like 10-20 of them running at once.
