I have a script on my site to block abusive bots, in this case abusive can be defined as too many requests in N time. In the years that this program has been active GoogleBot has never tripped it. In the last 3 days it has been banned 3 times. The ban is written into my htaccess. That, obviously, is not good! In addition to GoogleBot, the media bot was also banned.
I've adjusted the parameters on my script, and I'm praying that Google won't hate me. But I wonder why, after all this time, they have tripped my filter. Has anyone else noticed a change in the GoogleBot behaviour?
