DNS problems we all need to think about

Microsoft's problems may somedays apply to us.

the following is a clip from the article
According to Robertson, Microsoft or its network provider Akamai--which the
software giant apparently uses to distribute content across the
Internet--failed to create backup systems for distributing the DNS
information over the Net.

Instead, all of Microsoft's servers shared the same physical network--a
security flaw waiting to explode, Robertson said. "It is a poor design
choice to not hand out server addresses on different network blocks."

Other major networks, including America Online, Yahoo and Disney, have
backup servers on different networks, minimizing the threat from a single
Internet attack or outage.

Microsoft declined to comment on its network design.

in our own networks, the same applies for both DNS & DHCP.
