Free secondary DNS services

If you run an authoritative DNS server and serve your own zones you may know about the need to have decent secondary DNS servers, or "slaves", to back you up.

June 2015 update

I recently changed mine and followed recommendations by Frankb's page. My pick:
  • RollerNetwork: simple, IPv4+IPv6, supports DNSSEC, 2 locations; quick to update
    • they also provide logs of the transfers (useful to debug)
  • puck.nether.net: simple, IPv4+IPv6, supports DNSSEC, 1 location; fairly quick to update
  • freedns.afraid.org: simple, supports DNSSEC, 1 location; a bit slow to update
  • BuddyNS: fancy but does not support DNSSEC, so no
Just wanted to tell that so far these are great, so I pass the word as a thank you for the service they offer for free.

  2. I'm using FreeDNS.afraid.org to back-up my zoneedit DNS service, which is plagued by DOS attacks. FreeDNS.afraid.org seems to work fine.

  4. I have used puck for a couple of years with no problems but they seem to be plagued by downages lately and sometimes are off line for long periods. Too bad. It might be a good thing to look at the origin of the servers for Buddyns... India and the notorious Hezner network in Germany who are one of the most spam/hack plagued networks on the planet, so much so that I have blocked their entire set of IP blocks until further notice. Just sayin.
