Better that the problem was avoided all together like the OpenDNS service did. If you used OpenDNS for your DNS servers you never were exposed at all.

More info on this security issue here in the BBR Security forum: »Internet flaw could let hackers take over the Web
True - apparently the potential exploit of the flaw has been known for a while (recall reading a comment that the DNS system has been known to be broken for a while). OpenDNS is a good solution for someone with some knowledge but I am pretty sure that the big ISP's (Bell, Telus & Rogers in Canada) would not pre-configure their service to use someone else's DNS. And 99% of internet users would never even want to fiddle with those setting... unlike those of us here on DSLR that have a higher comfort level with these changes.

Unsure exactly what TekSavvy did to patch their system but I would guess (since they said that they are not on an MS system) that they upgraded their BIND from v8 to v9. But that is pure speculation because I can honestly say that I do not know what that last sentence implies wrt ease of an upgrade

Sometimes the nutjobs are 100% right:
