Today I went to visit a subdomain of mine that I use regularly, to find that it didn't work. After opening another tab to visit slickhouse.homeip.net it appeared that the DNS was non-existant. This domain is a 'catch-all' for my webserver, that ensures people can find their way around even if they mis-type a URL.
All my domains are registered with GoDaddy and the DNS is handled by ZoneEdit - but the aformentioned domain is provided by another Dynamic DNS provider - DynDNS. The reason for this is clear, if an update on ZoneEdit fails, I can fall back to DynDNS and force an update - and vice versa.
However, after finding a forced updated of the IP via DynDNS didn't work, I realised my account no longer existed either. It appears the DynDNS had deleted my account without any prior written notice!
And to think, 12 months ago, I was tempted to purchase their services for all of my domains. Imagine if you woke up one day to find your account (along with the related domains) had disappeared?
If any of you out there are currently using DynDNS' free service, let me know if you've experienced similar issues. If not, I'd recommend you look for an alternative Dynamic DNS service, as you too could end up in the same situation, without any written notice.
For those of you still looking for my 'fall-back' domain, it has been moved to hosting.slickhouse.com
