and a good thing, too. Those of us who have been around the block a few times will remember all those dire warnings in the early days of the internet's life. Hackers were going to close it down on an almost daily basis, and at times it seemed that they had almost succeeded - it was so slow.
The internet is now such an integral part of the planet's daily life that it would be nothing short of a disaster if it was effectively shut down by malicious hackers. That they have tried and failed is a tribute to those who have developed the technologies that enable the load that was previously carried by the internet's 13 root servers to be distributed to other computers around the world.
