My issue is that level3's dns has always been very fast, and more importantly, up... When google's dns is slow, level3 is fast... when my isp's dns goes down or wonky, level3's is up... I'd pay them $10/year to use them without the ads.
And then they have your entire history of internet activity, matched to you name, address and CC number. Fine if all you want is reliablility. For those who want to imped surveillance it is as bad as the ISP.
@karlshea was responding to @tracker1 who said that he/she would pay for the service. If someone is already willing to pay for the service, then I doubt this their major concern. You responded as if @karlshea was ignoring some requirement of the parent post...
