You NEVER want to block *.akami.net!!!!! That is unless you want to block a major part of the internet. Akami is one of the largest distributed data hosts in the world with 15000 servers in 65+ countries around the world. Blocking their servers is like saying "I don't want to have any of my internet data pass through a CISCO device" Their client list is here: http://www.akamai.com/en/html/about/customers.html and there are many more including Google, Microsoft and many more people use Akami for data hosting, and other services. - Marc
