Firstly there is no excuse for not having a secondary server.
There are plenty sites that off to do it free (some conditionally).
When your nameserver is down other sites cannot lookup the zones
served by it. Some people claim this is not a problem (especially
when the server is the site) however if everyone did this nameservers
would be clogged up trying retrieve answers from dead sites. You
also need to remember that nameservers are often shared between many
thousands of clients.
