I was surprised this morning to check my email and get only a handful of emails -- the lack of spam should have been a give away that something was wrong as usually I have to download between 300 and 500 spams per day. As the day went on, and mail slowed to a ridiculous trickle, I finally got suspicious and found that it wasn't possible to resolve the kerneltrap.org domain on the Internet. (I didn't notice right away locally as I have it hard coded in my /etc/hosts file) Connecting to my DNS provider's website I learned that for the first time in the five years I've used Zone Edit both servers hosting my DNS were down. The result being that http://kerneltrap.org/ was inaccessible for much of today.

I quickly added two more DNS servers to the domain, for a total of 4 now, and as the changes propagated the internet traffic returned to the pages. And my backed up mail started coming in. Zone Edit guarantees that with 4 name servers, there will never again be DNS down time for my domain.
