Some ages ago, in IT terms of time, Microsoft proclaimed, there is no such thing as a ping of death.
Shortly after, they couldn't keep a server online and had to go with a Slowlaris system for their FTP, claiming it was due to loading issues.
When those went down, they eventually admitted to the ping of death.
Fast forward past the Windows ME debacle to Win2k and its "bulletproof" security and the many, many, many, many, many, ad absurdium many's debacles.
I'll not even go into 2003, autorun, tens of thousands of security issues and even more bugs.
So, *why* is this considered news? Microsoft is the purest example of the Peter Principle that exists in the entire universe.
