It will be an issue with the front-end reverse proxying, rather than DNS, per se, I suspect...

Reading the blurb on the CloudFlare site, this is an uptime improvement service that sits, as some form of reverse proxy, in front of the actual Daz site.

Normally it is transparent. But if the site that CloudFlare is "protecting" is down, CloudFlare kicks in and serves up cached pages... or if it doesn't have a cached page, an error message.

It looks like CloudFlare is set up as a form of CDN, and is formed from a very distributed network of lots of proxy web server farms, dotted all over the internet.

When the Daz site was down yesterday, CloudFront kicked in with serving up those cached pages / error messages.

However it sounds like it has not reverted to normal service, for your part of the internet at least (it certainly has for my locality) when the actual Daz site came back online...
