where do people here sit with the DNS flaw?

I was listening to the excellent TWIT TV podcast earlier and a topic popped up about a serious DNS flaw that, potentially, would allow malicious people to impersonate almost any website on the Internet.

Just curious to how Drupal admins are taking this? is there need for concern or is this a hosting thing?

The podcast pointed people to http://www.doxpara.com/ which was setup by the guy who discovered the flaw in DNS.
