Lemmyverse historical data? (data.lemmyverse.net)

I am interested in checking out the historical growth of a particular community. Lemmy Explorer crawls for data about the Lemmyverse every 24 hours or something, and that data is made available on their website. But I can only find where to download the latest data. Is there somewhere that I can find historical data? Does Lemmy Explorer archive these anywhere, or does it just overwrite the previous data each time it crawls?

I think it over-writes every time. If you just want subscriber numbers, I've got data going back to to last July. Let me know what community you're after, and I'll send it to you.

Do you happen to have subscriber data on !caps@lemmy.world?

Yeah, but the community started before the bot at !trendingcommunities@feddit.nl did, lemmy.world had a broken API for much of August (hence the jump), and the subscriber count never changes that much otherwise, but here's what I have:

Incidentally, if you want to know how broken the Fediverse is right now, lemmy.ml is the only version that has both of your comments. piefed.social (my instance) has 1, lemmy.one (OP's instance) had the other one, and lemmy.world (where this community is hosted) had none (edit: this was before I made this comment, which has forced a bit of a re-sync).

Mostly because Lemmy has a hard time keeping up with the federation

Oh, right. The chat on GitHub is over my head, but I would have thought that solving the problem of instances sending every activity 2 or 3 times would help with that, since even rejecting something as a duplicate must eat up some time.

[-] testAccount@programming.dev 1 points 7 months ago

Yes but now it must wait for acknowledgement of a request (activity), before sending the next one. If one request takes 333ms means you can do max 3 requests per second. Now big instances like lemmy.world have activity above that so instances too far will perpetual lag behind
