AWS Web Application Firewall blocks ISP ranges?

Yes.

our network is a mix of content and eyeballs and they listed the whole 
thing.  This has prevented the local school district from using their 
text to speech application (for their deaf students) as well as others.  
This has also affected the local library and residences.

It's a PITA.

Thanks Amazon.
