We’re aware of ongoing federation issues for activities being sent to us by lemmy.ml.

We’re currently working on the issue, but we don’t have an ETA right now.

Cloudflare is reporting 520 - Origin Error when lemmy.ml is trying to send us activities, but the requests don’t seem to properly arrive on our proxy server. This is working fine for federation with all other instances so far, but we have seen a few more requests not related to activity sending that seem to occasionally report the same error.

Right now we’re about 1.25 days behind lemmy.ml.

You can still manually resolve posts in lemmy.ml communities or comments by lemmy.ml users in our communities to make them show up here without waiting for federation, but this obviously is not something that will replace regular federation.

We’ll update this post when there is any new information available.


Update 2024-11-19 17:19 UTC:

Federation is resumed and we’re down to less than 5 hours lag, the remainder should be caught up soon.

The root cause is still not identified unfortunately.


Update 2024-11-23 00:24 UTC:

We’ve explored several different approaches to identify and/or mitigate the issue, which included replacing our primary load balancer with a new VM, updating HAproxy from the latest version packaged in Ubuntu 24.04 LTS to the latest upstream version, finding and removing a configuration option that may have prevented logging of certain errors, but we still haven’t really made any progress other than ruling out various potential issues.

We’re currently waiting for lemmy.ml admins to be available to reset federation failures at a time when we can start capturing some traffic to get more insights on the traffic that is hitting our load balancer, as the problem seems to be either between Cloudflare and our load balancer, or within the load balancer itself. Due to real life time constraints, we weren’t able to find a suitable time this evening, we expect to be able to continue with this tomorrow during the day.

As of this update we’re about 2.37 days behind lemmy.ml.

We are still not aware of similar issues on other instances.


Update 2024-11-25 12:29 UTC:

We have identified the underlying issue, where a backport for a bugfix resulting in crashes in certain circumstances was accidentally reverted when another backport was applied. We have applied this patch again and we’re receiving activities from lemmy.ml again. It may take an hour or so to catch up, but this time we should reliably be getting there again. We’re currently 4.77 days behind.

We still don’t have an explanation why the logs were missing in HAproxy after going through Cloudflare, but this shouldn’t cause any further federation issues.


Update 2024-11-25 14:31 UTC:

Federation has fully caught up again.

                No, being a tankie isn’t only about supporting aggression / silencing people, it is specifically about romanticizing communism as some great philosophy that solves every problem and in extension sucking the D of Russia and China, while going “every other country bad” to the point of complete insanity.

                Otherwise rightwing US are tankies.

              A tankie is someone who sided with the authoritian government and their tanks against the one guy who stood in front of them in Tianenman Square.

              They say they’re communists but defend an authoritarian oligarchy…

              Authoritarians say they’re communist because they hate communism and don’t want people to think it’s a good idea. So they call everyone on the left a tankie.

              It’s a stupid label and 99% of the people throwing it around don’t understand anything about it and are just lying about what communism is.

          I haven’t really had that experience with anyone from .ml yet. There are a handful of actual tankies there but for the most part, from want I have seen, it’s mostly various forms of far left opinion which no one should be afraid of.

          Some people here do spend an unseemly amount of time complaining about them. Which is more toxic than anything they’re usually complaining about.

            A lot of them seem to be like the crazy Facebook crowd (not all).

            But that being said, unfortunately, as Lemmy grows, I’m seeing more of that in general where we slowly move away from a “scientific” oriented approach, to half-truths and biased information.

            So you’re probably right.

            But yeah, people do complain a disproportionate amount about them (I feel like a lot of people screaming “tankie”, are similar to the trump crowd people)…

              I didn’t get the sense of someone deliberately sowing misinformation however. Being misinformed isn’t a dealbreaker nor is a poor rhetorical style.

              I think it is important to continue forward with users with a wide range of sources. None of us have a monopoly on the truth and all of our ‘trusted’ sources palter and decontextualise their facts to some degree.

              I know it’s probably an unrealistic expectation but I’d rather mods, in general, had higher standards for curating civility in discussions.

        “Echo chamber” is often used as a criticism on the internet. But in real life, when you make friends, it’s with like-minded people, right?

              Not everyone on .ml wants to eat your dog. Just as not everyone on .world is Trolleyman.

              I’d say that the majority of people on the fediverse are capable of having a civil conversation on most topics. Some might have a handful issues that they dig their heels in over but can be civil if you comport yourself respectfully. And then there are a tiny minority of narcissistic zealot idiologues that try to maintain a narrow normative pressure on permissable opinions.

                Remember folks.

                This is how they infiltrate circles and twist them to right wing authoritarianism and extremism

                They send in someone who uses a soft approach as their opening gambit, talking about how they are good people, and how they don’t deserve to be excluded, and its really unfair to judge them for what they and their associates do, and that if you were really as tolerant and as leftist as you said you were you’d accept them, and engage with them, and sup with them.

                While handwaving any of the actual, legitimate, pointed criticisms as the actions of a “tiny minority of zealots”

                Its death by a thousand cuts, and what Hamartia here is doing is trying to do the first tiny cut. To try to make you feel unreasonable, and possibly even bigoted, for taking a stand againts the poor, innocent nazis/tankies/etc.

                You know why this hasnt been a significant problem until this past decade? Cause these people were punched in the mouth the second they started "Well, Ackshually~"ing in the defense of right wing fascist extremism. The second they started to fly their freak flags. Its why they have a whole underculture of co-opted symbology and secret coded language, because they were scared and had to hide, and needed a way to recognize eachother without risking a baseball bat to their jaw.

                And the reason we stopped doing that, is because this soft handed approach of theirs worked. Its why they dropped the coded language. Its why their freak flags are flying high and proud now. Its why they are openly, gleefully saying their absolute horrid, unfiltered hated with gleeful abandon now. Because what Hamartia is doing, worked. It got their foot in the door, and as soon as it was there, they crushed in with the entire party and took over.

                You can see where we are today, and its because we let their faux-reason, concern trolling, and paly acting exploit our tolerance.

                And you see what its gotten us

                And you see why its better to go back to the old classics of punching these motherfuckers in the mouth.

                So don’t let this soft hand propaganda being done by Hamartia and others sway you. Don’t let it make you feel unreasonable, or uncivil. They are manipulating you to open the door for the ones behind them that arent capable of feigning and playacting “polite” discourse in attempt to make you feel like you’re the bad guy.

                These people have no place in a polite and tolerate society. They are a cancer that seeks to destroy it, by exploiting our beliefs against ourselves. Its not paradoxical. Its not hypocritical. Its not whatever bullshit attempt they make next at trying to twist tolerance into a dagger for them to use to stab tolerance itself in the back and kill it to their extreme benefit, and to societies great loss.

      Unfortunately not entirely true. They have the largest Linux Community. To be precise, the big one.

      ProgrammerHumor is there as well. The Open Source and Privacy communties are very bigs as well there. Completely dwaring their .world counterpart.

          They get smaller when less people federate with that clown-shoe of an instance. The idea that the community inertia in those three communities is forcing other instances to remain federated despite wide-spread dislike and disdain for .ml users is absurd. Burn the bridge. The more it gets defederated, the bigger similar communities on less toxic instances can and will grow.

          Could you imagine using that logic in any other context? “I hang out with a community of KKK members because three of their members know a lot about Linux and have a lot of Linux-involved friends.” Give me a break.

            It happened that way with Beehaw. Beehaw used to be in the same position as lemmy.ml with some of their communities. But they decided to knee jerk defederate us and sh.itjust.works because we’re big. They stopped being the de-facto communities not just for us here but almost anywhere else. Defederation does curb this kind of network effect, and quickly too, especially when it causes the less active ones to inflate like crazy.

              Yeah. If anything the situation has become worse since that time. I was banned from the entire instance for a frank if somewhat critical discussion of Chinese history, even as I was trying to avoid contemporary politics because I knew that would get me in trouble.

              Anything other than fawning praise of the Chinese government is labeled racism and results in a ban.

        I think things like this can be helpful at curbing network effect. Which can only be really curbed by force. Beehaw used to have quite strong network effect in some communities too in the earlier days, but now, they have much less of a vice, and are actually much quieter than they were before.

      I’ve never had a positive interaction with Lemmy.ml. For me it serves as a quarantine space, and a set of pre-tagged users I don’t personally enjoy dealing with.

      …and I’m not particularly averse to Marxists sentiments either, but they’re certainly not good sales people, diplomats, or representative of their cause.

      Which is just part of their reputation now. Having a bad experience with a .ml user seems to be part of the lemmy experience. It’s kind of comical how consistent it seems.

        English
        1127 days ago

        Yes. Because it isn’t for FOSS enthusiasts… They use the .ml specifically to refer to an oppressive, violent, ignorant political ideology. Every bit as bad as capitalism. That’s a threat to anyone that disagrees with them left or right.

        A lot of older established communities are there by the circumstance of it being the oldest server. And not by any other virtue. In fact, there are a number like the KDE project that have their own instance. Completely detached from political ideology. Which is a wise decision. A lot of official projects don’t want to be associated with the regular hypocritical and disparaging remarks of the admin staff there

        I’ve been a foss enthusiast since the late 80s early 90s when I was in college. Used Linux since 94. Dabbled in BSD a bit before. Am solidly towards the anarchist left. And I block ML on principle alone. Authoritarians aren’t allies. And access to open source communities shouldn’t hinge on not accidentally crossing the fragile and hypocritical political ideologies of such groups. No place or group is perfect. But few are so flawed out of the gate.

              Would need to be one that restricts participation of the other party, Lemmy blocks are useless in that regard.

          In order for that to work there needs to be effort taken to curb persistent network effect like the utterly monolithic communities on lemmy.ml. When there isn’t any, they just get bigger and stronger. That isn’t something you can do by starting new instances, it has to be done by ones with a big slice of the pie, something new instances never have unless started just after the collapse of an existing one.

      • Draconic NEO

        We would adapt, just like when Beehaw was a significant amount of the userbase on Lemmy and they cut us and sh.itjust.works off, we adapted and they got smaller. Lemmy.world is a bigger server than lemmy.ml. Only reason their communities are still so big is network effect. Which would be curbed by them being cut off. As I’ve said already, network effect is curbed by force, taking away a choice, not providing 7 more choices while leaving the original.

    I’ve noticed some lemmy.ml communities looking surprisingly “dead” some days here and there but not thought much of it.

      I wouldn’t say usually, but they can happen from time to time for a variety of reasons.

      It can be caused by overly aggressive WAF (web application firewall) configurations, proxy server misconfigurations, bugs in Lemmy and probably some more.

      Proxy server misconfiguration is a common one we’ve seen other instances have issues with from time to time, especially when it works between Lemmy instances but e.g. Mastodon -> Lemmy not working properly, as the proxy configuration would only be specifically matching Lemmys behavior rather than spec-compliant requests.

      Overly aggressive WAF configurations tend to usually being a result of instances being attacked/overloaded either by DDoS or aggressive AI service crawlers.

      Usually, when there are no configuration changes on either side, issues like this don’t just show up randomly.

      In this case, while there was a change on the lemmy.ml side and we don’t believe a change on our side fell into the time this started happening (we don’t have the exact date for when the underlying issue started happening), while the behavior on the sending side might have changed with the Lemmy update, and other instances might just randomly not be affected. We currently believe that this is likely just exposing an issue on our end that already existed prior to changes on lemmy.ml, except the specific logic was previously not used.
