  • Bluesky is (in theory) federated, but I think you can’t run your own server yet. We’ll see if they keep their promise.

    Its protocol has some improvements over ActivityPub, for example you can use a domain name you own as your username even if you’re not hosting your own instance, and your user identity is portable in that case - you can move to a different instance but keep the same username.



  • Well it isn’t shared before the upstream server, that’s what FTTH is.

    FTTH just means that there’s fiber going into your house.

    Most residential fiber internet connections use a technology called PON (GPON for gigabit or XGS-PON for 10Gbps). My understanding is that the fiber from your house goes into a splitter box in the street, which takes fiber connections from many customers (usually either 32 or 64 customers) and multiplexes them into a single fiber by either using different wavelengths of light or by time multiplexing. Upstream from this, bandwidth is shared.


  • The bandwidth is still shared… It’d be prohibitively expensive to have dedicated bandwidth just for your connection, and most customers don’t need anywhere near that. Unlimited, dedicated 1Gbps is around 320TB of data per month.

    A business-grade connection has fewer people sharing it, but it’s still shared. The only fully-dedicated connections are enterprise-grade connections (like in a data center), and even then it’s an upgrade that costs quite a bit. :)
