[PNGNOG] Interesting presentation from PTNOG

[Mark Prior <mrp@mrp.net>]

Hi there,

The Portugal NOG was held recently and the presentation material is now 
online. I found this talk from John Graham-Cumming of Cloudflare 
particularly interesting and so I thought I would share a pointer to it.

TL;DR Register your ROAs :-)

The other talks can be referenced from <https://ptnog.pt/en/ptnog4-2/>.

Regards,
Mark.
