Thanks for this write-up Alun! I just joined the DisNOG – such a good idea. Also, if it's helpful to you and @Vesna, over the years I've worked to update the Wiki entry on NOGs: Maybe it'll be helpful as well! Lastly, one thing that could help is if there was a better understanding of which NOG corresponds to which place. Sometimes it's obvious like UKNOF, but not always.
