Neither of my posts from yesterday and today have made it out to their communities' home instance (lemmy.world), and neither has received any comments or votes. It seems like something to do with outgoing federation is stuck.

Edit to clarify:

The problem I'm seeing affects posts. I don't know if it affects comments.

It's possible that it only affects lemmy.world communities, but it definitely affects them even on other instances. Neither of these posts are showing up on any remote instance that I've seen:

6 days later, it's happening again:

This might explain why my posts aren't getting enough downvotes.

[–] [email protected] 7 points 2 months ago (1 children)

Or you're just not posting trash enough content.

There's no need to be rude.

Slrpnk seems to be receiving your posts

[–] [email protected] 3 points 2 months ago (1 children)

Looks like it received this one, but not the ones I mentioned that are in lemmy.world communities.

[–] [email protected] 3 points 2 months ago (4 children)

From my experience, lemmy.word can take hours to federate to no matter the instance. I think they might be using some weird shit for "last mile".

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

Would a federation problem on lemmy.world block propagation to slrpnk.net? That would be a weirdly inefficient network design.

That's (an example of) what I'm seeing right now. It's abnormal.

[–] [email protected] 2 points 2 months ago

Hours wouldn't raise my attention. I'm talking days.

I think they might be using some weird shit for “last mile”.

Given that lemmy.world uses Cloudflare, I wonder if their server is overloaded enough to sometimes exceed Cloudflare's 100 second timeout, triggering http-524 errors during federation.

Can't wait to see what happens when/if they move to sublinks. How much worse can they get

[–] [email protected] 2 points 2 months ago

How much worse can they get

I think kbin.social showed us that overload can get much worse.

[–] [email protected] 2 points 1 month ago

From experience sh.itjust.works sometimes has this problem as well.

They also have one thing in common: Cloudflare

Perhaps it's getting "protected" from federation considered a DoS.

Completely off-topic:

I'm surprised to learn from the comments here that people on other instances subscribe to this sdf-specific community. I have no idea why they would, but it somehow makes me happy.

[–] [email protected] 3 points 2 months ago (2 children)

Lemmies front page is not that big.

[–] [email protected] 3 points 2 months ago* (last edited 3 weeks ago)

On the contrary, its too much stuff I'm not interested in, and/or actively disinterested in, and not enough of the rest. OTOH, I don't even remember the exact topic of this community or instance.

Seems techy and not full of absolute garbage, and that's more than enough for me.

[–] [email protected] 2 points 2 months ago

Definitely not

(And it's usually the same people everywhere)

Thanks. So a post to this lemmy.sdf.org community reaches your instance, but my posts to lemmy.world communities do not.

Welcome. Have you been in dialogue with them about it?

[–] [email protected] 2 points 2 months ago* (last edited 2 months ago) (1 children)

Welcome, yourself. ;)

No. I haven't made an SDF board account, since I'm already overloaded with online accounts. I'm not aware of another way to reach them.

[–] [email protected] 1 points 2 months ago (1 children)

Hah! Thanks. Check the sidebar, iirc.

[–] [email protected] 1 points 2 months ago* (last edited 2 months ago) (1 children)

The sidebar shows only a moderator. I assume they can see this discussion already, but if you have reason to think they relay problem reports upstream when pinged, I suppose I could ping them.

[–] [email protected] 2 points 2 months ago (1 children)

A try is the only thing that can beat a fail, I suppose?

[–] [email protected] 1 points 2 months ago* (last edited 2 months ago) (1 children)

I'll take that to mean you have no particular reason to think that. As a general rule, I don't like to poke the mods about operational problems that they are likely already aware of. They're not sysadmins, after all, and having been in those shoes, I know extra demands for attention can get tiresome.

But if this persists for long, I might poke the mod. If other people start noticing it as well, perhaps they will bring it up, too.

[–] [email protected] 1 points 2 months ago (1 children)

What can any of us itt do?

[–] [email protected] 1 points 2 months ago

The point of posting is to create a record of the failure, for reference when someone wants to find a pattern or potentially fix it.

Several of us in this thread have already collected relevant information that might help pin it down.

Several times in the past, I have seen SDF members who also have a board account relay problems reported here to the board.

As for you yourself, maybe nothing? That's fine. Feel free to ignore it.

Seeing this on a random dutch instance I joined when my favorite machinist reddits each chose it. No regerts

[–] [email protected] 1 points 2 months ago

Done. Thanks!

[–] [email protected] 1 points 2 months ago

Thanks, but the posts in question are not showing up on your instance, either.

It doesn't solve this problem, but it could be useful some day. Bookmarked; thanks.
