He also runs an excellent ISP in the UK called AAISP which I can highly recommend (https://www.aa.net.uk)
AAISP build their own core & customer networking devices/routers from scratch (not Linux based) in the UK. They are fascinating to use - a completely different evolutionary tree to any other networking kit I've used. Some unique features.
