Yeah, the entire setup is quite finicky still. Part of me thinks Fediverse is forced into the spotlight by Twitter (Mastadon) and Reddit (Lemmy), and the whole thing is not quite baked yet. Don’t get me wrong, having a more open space is great, but there are so many things that’s not quite ready for prime time. I hope the dev team behind the platform (not the self hosted instance admins) will be more open to ideas and rapidly improve the platform.
I am new to the fediverse, and I don’t use Friendica, so I could be entirely wrong about this. However, from what is described, perhaps Friendica has some sort of feature in which would trigger your instance to go out to fetch some data from another instance. Someone exploited this feature, spammed your instance with content from assortment of subdomains on the *.activitypub-troll.cf domain, and most if not all of them are probably non-existent. As result of that, your server is re-checking every 10 minutes to see if they’ve came back online. This would also explain why shutting down the Friendica service resolved the problem for you.
Yeah, I really do think we need both:
!gaming@... or !gaming@ which aggregates !gaming@instance.a, !gaming@instance.b, … etc. that I’ve subscribed to into a single feed; and
#gaming which I can put !gaming@..., !pcgaming@..., and !consolegaming@... into a single collection.
This way we’d get the flexibility to pick and choose what we’d want to see more easily.
Are there ways to manage lists of such? For example, on the former platform that doesn’t deserve a call out, you can do “me_irl+meirl” and aggregate both into one feed. This makes reading the (albeit potentially cross posted) content in a unified feed much easier.
Another similar point I’m having a hard time getting over is that with a centralized platform, it is easy to go to “Subject A”, and see everything on that subject. However, now I need to see “Subject A@lemmy.world”, “Subject A@lemmy.ml”, “Subject A@someother.instance”… Yes, I could subscribe to them all, but this ultimately end up creating a noisy home feed with also “Subject B@lemmy.world”, “Subject B@lemmy.ml”, “Subject C@lemmy.world”, “Subject D@lemmy.ca”, … etc. all baked into one feed, as opposed to just something focused on “Subject A”.
Lastly, discoverability leaves a lot of room for desire. Today, I’m fairly new to Lemmy, I am actively seeking out communities that I might be interested in, across multiple popular instances, and hoping that federation is enabled between the two instances. Tomorrow, I’d find that I’m subscribed to too many (see the noisy main feed issue above), and I’d remove a bunch. Next week, am I likely to go to the Join Lemmy directory to find new instances, and add “duplicate” communities from newly popular instances? I think not.
I think the long term survival of the platform (to expand beyond just us tech nerds that hate the former platform) will depend a lot on streamlining this workflow to make content discovery much more consistent. Even a simple option where a pseudo “!Community@” (with no instance) feed that aggregates all the “!Community” regardless of instance that you’ve subscribed to, might go a long way.
Unfortunately, it would appear that there’s not without very significant problems… I’m commenting to your comment via my lemmy.world account because I’m not seeing your comment on my instance.
If you do get it working, and find ways to resolve issues I’m having, please do share back so I can get my instance fixed as well! Thanks!
