I think the group wants to know what problem you're trying to solve. Obviously if you block something, there will be a timeout in getting to it. 

What is broken that you're trying to fix by blackholing them?

Customers see timeouts if I blackhole Google network. I looking for 
alternatives (other than stop providing IPv6 to customers at all).
