"BGP at home": getting a DIA circuit installed at home
The infrastructure underlying AS54316 -- the network supporting the services offered by the AP Foundation -- has historically been based out of a datacenter in NYC (NetActuate in Telehouse Chelsea).

The IPv6 Transition

In light of the recent cancellation of the queer.af domain registration by the Taliban , the fragile and difficult nature of country-code top-level domains (ccTLDs) has once again been comprehensively demonstrated.
