As per this post, it seems Lemmy World is having federation issues. I've had some of my posts and comments get suspiciously low response, so I've looked into it and it turns out that many of them aren't showing on other instances.

Here's an example: my Payday 3 post is only visible on Lemmy.world:

Meanwhile, in other instances, it doesn't show up at all:

It's not clear if this issue is exclusive to this instance but I thought I'd give people a heads up. I reposted and now it showed up in other instances. If you feel like you're getting no response from other communities, check on another instance if your content is visible, otherwise repost it.

It isn't just Lemmy.world, and isn't limited to v0.17 either. Lemmy.ca, which has been running v0.18 for days, is also not seeing a lot of federated content, nor accurate community subscription counts from other instances, including lemmy.ml and others running v0.18. I'm posting this from my .world alt because .ca is showing zero comments in this thread.

There have been several not-so-friendly comments made about the issues by someone in [email protected], calling out the site admins of .world and .ml for not sharing their server logs, and the overall silence on the issue. The user's concerns are genuine, but I don't agree with their behaviour.

I suspect the devs were/are completely overwhelmed by the mass influx of redditors these past two weeks. I assume someone is looking into it, but frankly I wouldn't blame anyone if they chose to step away for a few days. I think a lot of folks (particularly "the masses") forget that these are largely volunteer efforts, by people with day jobs.

Thanks for your reply. This site isn’t even a month old and the user growth is spectacular. Lemmy hasn’t ever been tested with these amounts of users.

I’m sure the devs are doing their best in getting it all more performant. Meanwhile the team at lemmy.world is trying to get a grip on what’s happening with federation. There’s not much to be found in logs, anyone who can help troubleshoot this let us know. The only real adjustable setting is the federation workers. We’ve apparently either set that too high or too low. I’m gonna set the log level back to info on the hopes we get some queue stats…

To be continued

No worries, and I completely sympathize with the situation. My hat is off to you site admins, and the lemmy devs, for keeping things afloat these past couple of weeks, often at great expense of both time and money. I am confident that all of these kinks will be ironed out in the coming months, and in the meantime I am happy to have a few alts to hold me over.

[–] danc4498 12 points 2 years ago (2 children)

Back in my day 1 month old sites had 0% downtime and no reported glitches. 1 million daily active users! There's no need for beta software either cause 2.0 was always the perfect release.

Those were the days!

Looks like grandpa has gotten into the horseradish again.

[–] A_A 1 points 2 years ago

"fediverse" x "lemmy" - - proves to be too complicated to work reliably on available infrastructure ...while early websites were quite simple and so very efficient.

[–] deweydecibel 4 points 2 years ago (1 children)

So to be clear, we're fairly certain this is a technical issue and not because of something other instances are doing?

[–] thayer 12 points 2 years ago* (last edited 2 years ago)

It's almost certainly technical issues relating to scalability. The user I mentioned above has created a community for tracking several performance issues that are likely impacting the platform now that user and post counts have increased exponentially.

[–] cashews_win 9 points 2 years ago* (last edited 2 years ago)

for not sharing their server logs

WTF do users think they have a right to see these at all? Just because Lemmy is open source doesn't mean you get to run the damn thing.

Also my condolonces on you being a Canadian.

[–] [email protected] 5 points 2 years ago

I sympathize. I just hope it's not true. Friday and Saturday of this week are likely the second and bigger wave of redditors coming over as their 3rd party apps get disabled on/after 30th. I hope the admins are preparing for it.

[–] BobbyBandwidth 28 points 2 years ago* (last edited 2 years ago) (1 children)

Correct me if I’m wrong but .18 lemmy doesn’t support captcha, so lemmy.world is waiting for a patch before updating so we don’t get flooded with bots.

Edit: fixed typo

[–] dezmd 13 points 2 years ago (2 children)

Just clicked on a Futurama related post on Lemmy.world front page, it opened wtih this MLB Game Thread as content instead of what I clicked on. **This is happened more than once. Previously I thought I derp clicked on the wrong item **

[–] Sunforged 10 points 2 years ago

This has been happening to me for at least a day now. Reloading fixes it and brings you to the post you thought you were in.

Funny thing is sports communities are the ones I block as I come across them, and this glitch circumvents blocked communities.

[–] Couldbealeotard 2 points 2 years ago

I'm not kidding when I say I opened a meme post and the picture was from the "bulges" page. The comments were the correct meme post comments though. I went back and forward again in my browser and the image was correct.

[–] ericjmorey 12 points 2 years ago* (last edited 2 years ago)

Lemmy.world is definitely having federation issues. Lemmy in general is having a lot of federation issues, but it looks like lemmy.world is being effected more so due to the number of accounts and activity on lemmy.world in combination with different versions of lemmy handling messages a bit differently with different implicit assumptions.

[–] rcmaehl 12 points 2 years ago* (last edited 2 years ago) (2 children)

I believe this is a side effect of the 0.17 vs 0.18 split which unfortunately wasn't backwards compatible. Once 0.18.1 rolls out with readded captcha everything should be hunky-dory again.

[–] simple 8 points 2 years ago (1 children)

Fingers crossed it doesn't take that long!

[–] chicane 3 points 2 years ago

Interesting that’s it’s been days without a minor beta at all. Where in the race for 0.18 the updates were 12 hourly at one point. Guess all the devs burnt the candle at both end. Much appreciated ❤️

[–] danc4498 1 points 2 years ago (1 children)

Was [email protected] the instance that was not showing the post?

[–] simple 2 points 2 years ago (1 children)

Yes, I ended up reposting there and it shows up now.

[–] danc4498 1 points 2 years ago

Maybe it's just the version difference, then. 🤞

[–] [email protected] 8 points 2 years ago* (last edited 2 years ago)

Workaround, I had to do the same on kbin.

Editing your comment triggers another sync, often an edit will make the comment or post synchronise to all other instances.

[–] necropola 7 points 2 years ago

That's pretty much what I yesterday called the lemmy.world bubble.

[–] dragontamer 7 points 2 years ago* (last edited 2 years ago) (1 children)

To add some specificity to this:

I've been unable to post to [email protected] or [email protected] successfully. And the comments seem to be failing to load at all.

Here's to hoping its the .18.x vs .17 issue. But I figured I need to post an official report of my problems somewhere, and this topic seems the most applicable location.

I've also been "Subscription pending" on [email protected] for... at least 20 minutes now. Suspiciously long times to get that resolved.

[–] dragontamer 1 points 2 years ago (1 children)

5 hours later, I'm still "Subscription pending". I dunno if this is related to the issues, but I figure I should document the problem here.

[–] dragontamer 2 points 2 years ago

Almost a day later, "Subscription pending". I'm guessing its this slow-federation issue that probably will be fixed with .18 upgrade (or maybe lemmy.ca needs to increase its federation workers?)

[–] SpezCanLigmaBalls 6 points 2 years ago (1 children)

If it was reposted and worked that’s not a federation issue right? Could it be that world isn’t on .18 yet?

[–] necropola 3 points 2 years ago
[–] [email protected] 6 points 2 years ago (1 children)

There should be a fix in a day or two, there was an issue with captcha to my understanding.

[–] CH3DD4R_G0BL1N 1 points 2 years ago

Ruud has said he doesn't know if any .18x update will fix these issues

[–] krayj 4 points 2 years ago

I'm very new to Lemmy and have already been experiencing this problem just testing how commenting to a federated community on another server works. It doesn't/hasn't worked for me yet in controlled testing. I've been assuming it was a problem with the other lemmy instance where the community is created/hosted but now I'm rethinking that assumption.

Usually, not assigning sufficient resources at a workload just causes the backlog queue to get longer, but in the case of lemmy it seems to result in some items never getting processed at all. That's an odd behavior for a backlog to have.

[–] heili 3 points 2 years ago

I've had difficulties with responding or commenting on posts on federated servers. Comments work just fine if I'm on this instance, but threads on others it just never posts.

[–] code 2 points 2 years ago (1 children)

I got a report earlier that my community wasn't showing up on https://browse.feddit.de earlier as well, but it's back now. I'm not sure how it works but I assume it's related.

[–] CAVOK 2 points 2 years ago (1 children)

Any idea on that 0.18.1 release? I have no idea how much work is required to add re:capcha. Are we talking days, weeks or months off work?

[–] necropola 5 points 2 years ago (1 children)
[–] [email protected] 4 points 2 years ago (1 children)

It just got approved after some edits

[–] necropola 5 points 2 years ago* (last edited 2 years ago)

... and merged to LemmyNet/lemmy:main 🙂

[–] possiblylinux127 1 points 2 years ago

This is why its a bad idea to have massive servers
