We had the similar thought, but the DNS entry would point to our local cache so
people could still get patches. We decided that it wasn't appropriate to mangle
DNS records belonging to others; Microsoft should be the one to make that
choice. Instead, we decided the best approach was resolve the problem on
network edge - clean and patch.
Regardless of the DDoS Saturday, access to windowsupdate is limited due to patch
downloads now, so we made relevant patches available on our local network.
