Over the past few years, as I’ve moved into VPS-based hosting, I’ve also started to use my VPSes as additional DNS servers, keeping the professional hosted-DNS for geographical and connectivity diversity.  As this incident has pushed me along in making sure that every domain I host has DNS from at least two different providers, I came to the conclusion that, given that I already have one commercial DNS host (giving me three nameservers), the best economics were for me to get a super-cheap VPS to run as only a nameserver.  While not the absolute cheapest, JustGotVPS.com is probably the best price-configuration balance, especially at their cheapest ($5/mo and $8/mo) plans, and they discount for longer-term prepayment.  There’s an entry for them, as well as numerous other VPS options around the $5/mo price point at lowendbox.com.

The tradeoff for this versus a commercial DNS host (since in both instances I’m paying about $60/year) is that the commercial host gives me three diverse nameservers but limits the domains, etc., whereas running my own VPS-based nameserver gives me only one host but substantially greater flexibility.  I would also note that I chose to get a cheap VPS box from some provider other than my primary VPS provider so that my new additional nameserver would not be in the same datacenter and on the same internet links.

I also have been using EveryDNS.com, a free DNS host, for additional backup (I’ve donated since I’m using them on several domains and they seem to provide a good service), but having used GraniteCanyon and others in the past, I don’t consider a free DNS host as a serious alternative to a commercially-provided option.
