"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).

Making Your Connection Bad
This is directly inspired by Engineering for Slow Internet. I figured I’d give running with dogshit internet on my desktop and phone a go to see how poorly (or well!) specific applications behave. This is not an in-depth review of the behavior, but just my general impressions running for a few hours on 200kbit…

WireGuard: Beyond the most basic configuration

Since I worked on ActivityPub which connects together Mastodon , Sharkey , Peertube , GotoSocial , etc, etc, etc in the present-day…

Europe's Internet resilience mitigates impact of submarine cable cuts
Two recent cable cuts that occurred in the Baltic Sea resulted in little-to-no observable impact to the affected countries, in large part because of the significant redundancy and resilience of Internet infrastructure in Europe.
