Quoting prairiebladerunnerDislikedHungry --- they haven't built an isp that can withstand all attacks. If attacks can crash the isp's for the Pentagon, White House, Microsoft, anything can crashIgnored
At least parts of it.
A Britisch 'hacker' got caught when he was looking for UFO evidence on Pentagon servers. All he had to do was look for blank passwords.
So some parts of the Pentagon have lousy protection.
May the pips be with you.
