OK, I’m biased. But I think OpenDNS CacheCheck is remarkable. Very simple, sure: you can see what address OpenDNS has for a domain, and ask OpenDNS to refresh that address if it’s not correct. Nothing more. Read what I wrote on the OpenDNS blog for more.
But if it’s so simple, how come no one has done it before?
I moved DNS for this domain, pencoyd.com, back in November 2004. I’m hardly alone in having warned people ahead of time, and then being relieved when the changes were propogated (or propogating).
I know I would have jumped to use this kind of tool, even though I did lower my TTL setting before making the switch. If you have the chance, wouldn’t you want your website to be visible as close as 100% of the time to as close to 100% of the Internet as possible?
OpenDNS does not equal the Internet as a whole. Not even close. But maybe we can start something here?
