Hacker Intel is reporting that Microsoft is weathering the storm via undisclosed measures. Could it be that "www.microsoft.com" is now a CNAME for "www.microsoft.akadns.com"? For those that can't take it further, "akadns.com" is Akamai. This means that Microsoft is "leaning into the wind" by providing more service capability than the Internet bandwidth can load.
Not to restart the argument but this method is more irresponsible as the one used by SCO in that ISP's will end up paying more to the backbone providers.
It IS an interesting solution though. I wonder how much MS is paying for the distributed website.
