After EveryDNS and EditDNS's outage, I have finally got my act together to have this redundant and free DNS running for some of my domains. I know both EveryDNS and EditDNS have 4 geographically separated servers, however during the event when the vendor is targeted for DDoS, I am still suffering downtime when their servers stuggle to stay alive. Therefore, instead of having your zone resiting on only one free DNS provider, you can get your domain hosted by both of them. Therefore just in case all servers of one provider get DDoS'ed, your domain can still stay visible on the net as the servers from the other provider are still answering requests.

One of the things that is worse than having your web site going off-line — DNS servers for your domain are under DDoS attack that renders your entire domain resolvable. That’s something HostingFu is facing at the moment.

EveryDNS was founded in June 2001 by DNS expert David Ulevitch, providing free DNS services to the Internet community. From their website:

We provide static DNS services as well as many advanced services such as Dynamic DNS resolution, Secondary service, AXFR service, and domain2web redirection. Of course, our primary service is free DNS.

New sign ups can get 20 domains and 200 records hosted for free. If you support them with once-off donation, these limitation will be lifted. EveryDNS currently hosts 92,000+ domains and 250,000+ records at the time of writing — that certainly marks them one of the biggest free DNS providers on the Internet.
