Interesting, I've always thought of the registrars as a pretty critical single point of failure. Does anyone have a creative solution for this?
Static IP with DNS backup.

Basically, the device uses the same static IP and if the login for it doesn't work, check the DNS to refresh the new static IP. Check backup DNS if the first one fails for login. Pretty straight forward really, that's what my Vonage router does, it can work in a DNS outage.
That's a good idea, but the problem with it is that the device has to support it. That doesn't translate well to a web infrastructure, or any email where the user has to input the information to reach the site.

I was thinking of something along the lines of multiple registrars for a single domain ... and if one returned an NXDOMAIN or any other sort of error, DNS would check the secondary registrar. I think my idea would require a significant change to the entire DNS infrastructure though. :)]]> http://www.dslreports.com/forum/Re-Single-Point-of-Failure-21794038 Fri, 23 Jan 2009 13:19:08 EDT Re: Single Point of Failure http://www.dslreports.com/forum/Re-Single-Point-of-Failure-21793973
How about, don't dick around with DNS settings when you're doing a renewal? If there's one thing I've learned about DNS, it's "one thing at at time". If you're doing a transfer, don't switch hosts for a week or so. If you're moving to a new host, don't try to transfer registrars. ]]> http://www.dslreports.com/forum/Re-Single-Point-of-Failure-21793973 Fri, 23 Jan 2009 13:08:29 EDT Re: Single Point of Failure http://www.dslreports.com/forum/Re-Single-Point-of-Failure-21793949 said by Matt:

Not a very good one. You could have a primary / secondary setup where you might have sipserver.primarydomain.com and sipserver.secondarydomain.net and have your domains registered at two different places. Your equipment would have to support this and you would have to use DNS servers with different domains with different registrars.
That's all I've been able to come up with also. I was thinking more related to web infrastructure, so in my case we'd have to somehow notify our clients to use a different FQDN. Not exactly ideal or really even feasible at all.]]> http://www.dslreports.com/forum/Re-Single-Point-of-Failure-21793852 Fri, 23 Jan 2009 12:44:01 EDT Re: Single Point of Failure http://www.dslreports.com/forum/Re-Single-Point-of-Failure-21793848 http://www.dslreports.com/forum/Re-Single-Point-of-Failure-21793848 Fri, 23 Jan 2009 12:42:38 EDT Re: Single Point of Failure http://www.dslreports.com/forum/Re-Single-Point-of-Failure-21793839 http://www.dslreports.com/forum/Re-Single-Point-of-Failure-21793839 Fri, 23 Jan 2009 12:41:18 EDT Single Point of Failure http://www.dslreports.com/forum/Single-Point-of-Failure-21793779 http://www.dslreports.com/forum/Single-Point-of-Failure-21793779 Fri, 23 Jan 2009 12:31:49 EDT
