As I understand it, no one really knows. They refuse to tell anyone.

In the experience of the community what causes the “Unusual traffic”
messages when doing google searches? This ISP network hands out public IP
addresses to each and every customer. No batting going on.  Does Google
typically drop entire /24’s into this if they see an issue?  The initial
troubleshooting we have done involves disconnecting the customer router and
going direct with a laptop.  Still the same captcha.  We clock “I am not a
robot” and the search goes through, but it re-appaers the next search.

Looking for a direction to look.  What typically causes this? I know what
the page says, but looking for specifics.

Thanks
