Hey Constantine, John came in with a technical issue. If you have nothing worthy to say about it specifically, it's best to keep quiet. Thanks! Ryan On May 30 2020, at 11:52 am, Constantine A. Murenin <mureninc () gmail com> wrote:
When you're not paying for service, you're not the customer, you're the product. I don't understand why anyone, especially anyone frequenting NANOG, would use Cloudflare for their DNS. Cloudflare runs a racket business, and their whole business model depends on them being a monopoly; plus people buying into the vapourware that they offer. When have monopolies been good for any industry? There's plenty of evidence of Cloudflare 1.1.1.1 not working correctly; I'm sure one of their employees (or the CTO!) will show up shortly to say otherwise! C.

Seems odd that Cloudflare DNS would apparently loose complete track of a major US domain name like usbank dot com Or am I missing something? - John -- John Sage FinchHaven Digital Photography Email: jsage () finchhaven com (mailto:jsage () finchhaven com) Web: https://finchhaven.smugmug.com/ Old web: http://www.finchhaven.com/
