Technical experts blame Microsoft's design decisions for exacerbating its woes. All the affected Microsoft sites rely on just four Windows servers, located in the company's Canyon Park data center, to forward users to the right destination via the Domain Name System (DNS).I won't launch into a lecture about redundancy, DNS, and how a mega-corporation like Microsoft ought to know better. But I'd really like to. I just want to spare you all; you know the drill.
Because all four DNS servers -- which translate names like microsoft.com into its 184.108.40.206 numeric address -- share the same routers, all are vulnerable to hardware glitches or a technician's error.
