Securing the BGP or controlling it?

I agree, its unfortunate that so many people no longer require route registration.  Not that it would solve all the issues.  Tom School, Todd Underwood and I present some  work we did looking @ this @ nanog in LA a while back. Unfortunately we could never find time to take it to the next steps.

What we need (as operators) is to get better at ensuring that advertisements
are coming from the valid owner of said address space. What we don't need is
a separate governance model which I worry this article is trying to imply. I
still use RADB but I hear not every peer/provider checks there anymore? This
is hearsay so interested in other opinions.

As far as the mistakes pointed out in this article one can be assured that
these things are bound to happen. The youtube situation could have been
prevented if the peer opening a filter (and responsible for announcing out)
had reach to a system where the other peer's advertisement can be verified.
I don't think leaning on competency is a good way to go about solving this
problem, we need a system or model in place to ensure we have a trust and
verification system.
