Trying to figure this out as in the recent threads a few people said that Bluesky was federated, but it didn't seem to actually be the case.
https://bsky.social/about/blog/02-22-2024-open-social-web in February announced that Bluesky would allow federated servers
The Bluesky documentation on the topic isn't very clear. They mention Bluesky.social a lot, as if it's supposed to be the one central server other PDS need to federate with:
Bluesky runs many PDSs. Each PDS runs as a completely separate service in the network with its own identity. They federate with the rest of the network in the exact same manner that a non-Bluesky PDS would. These PDSs have hostnames such as morel.us-east.host.bsky.network.
However, the user-facing concept for Bluesky's "PDS Service" is simply bsky.social. This is reflected in the provided subdomain that users on a Bluesky PDS have access to (i.e. their default handle suffix), as well as the hostname that they may provide at login in order to route their login request to the correct service. A user should not be expected to understand or remember the specific host that their account is on.
To enable this, we introduced a PDS Entryway service. This service is used to orchestrate account management across Bluesky PDSs and to provide an interface for interacting with bsky.social accounts.

Self-hosting a Bluesky PDS means running your own Personal Data Server that is capable of federating with the wider Bluesky social network.

The custom domain name is still something else, and does not seem to require a PDS: https://bsky.social/about/blog/4-28-2023-domain-handle-tutorial
So, to come back to the title question, do people know of an example of PDS that can be used to access Bluesky without being on the main server?
Wow, that's very high, thanks!
Lemmy.world used to cost that much, but I think they downscaled a bit recently, or are at least planning to as the current growth of the userbase has slowed down.
I was actually surprised by that 150 figure when I first read it, as it is much cheaper than what the BlueSky documentation makes it sound.
It is certainly possible to collect that much in monthly donations, but then again... how do you build a loyal base of supporters for running a mostly hidden piece of infrastructure? People always complain about the instance focussed nature of the fediverse, but the ability to build communities around them and get people actually emotionally invested in their home instance is IMHO rather a strength of it. That is also why I am slightly sceptic of easy account migration tools, as it devalues the instance as yourhome base to a certain extend.
Yeah, the instance-focus aspect of the Fediverse is a good thing. You are a good example with slrpnk.net, but dbzer0, all the language/country-based instances (feddit.org, jlai.lu, aussie.zone, lemmy.ca, feddit.uk) also have their own culture and feeling. That's cool to see.
That's definitely a thing for generalist instances. I don't really think there is much of a lemm.ee culture for instance. Which is also okay, some people just want access to Lemmy without a strong instance identity.
