I have been a za customer for over 10 years. I have za 9 on my w7 64bit and my netmon sees:
a184-84-210-59.deploy.akamaitechnologies.com even if I block whole subnet 184 or turn on internet lock.
I also have za 10 on my xp sp3 and I cannot block out Akama there either.
Tech support says ZA uses Akama so customer cannot block.
