Hey everyone, so as I’m sure everyone is aware Lemmy.World has been experiencing several outages throughout the last few days.
We have been investigating the root cause of these outages but believe that they are related to our current hosting provider (Hetzner) blocking access from ClouldFlare as (we think) they believe that our CDN is a DDoS’er, and is causing these disconnects to our backend server, problematic for sure.
We’ve opened support tickets with our current provider and are awaiting a response. We have no issue with being as transparent as possible with downtime. Anyone that is curious, can feel free to check out https://status.lemmy.world and https://dash.lemmy.world for up to the minute outage information. We are also looking into other fediverse friendly methods of posting status and outage updates
In the meantime, we are evaluating alternative hosting options and solutions to provide a high level of reliability to you, our users. Really, we want to say thanks to everyone for soldiering through all our technical growing pains.
Cheers
- LW Infra Team
As always, the transparency is appreciated. Some growing pains are certainly to be expected

So, by transitivity, transparency is metal?
We had an aquarium with transparent fishes, where you could see all their insides, that was pretty metal
So yeah i think we’re onto something here

Whenever I get frustrated by the outages I remind myself: still better than reddit.
Thanks to lemmy I don’t doom scroll anymore because either there is an outage or I read all the new content I’m subscribed to in 10-20 minutes
That’s mostly how I redditted for years. It was mostly for those moments in between things, on the toilet, laying in bed at night. Not something I did for long periods of time.
Look at this guy with his reasonable social media use. YOU THINK YOU’RE BETTER THAN ME??
Scrolling a few miles or so a day isn’t too bad, is it?
Huh, I could keep up with my daily feeds before, now not so much.

It’s your fault for not pitching in and making lemmy more stable. There, happy, you’ve been blamed :P

Plot twist: unlike Reddit, with Lemmy that would be a legitimate option! Ain’t Free Software and federated networks grand?
What is the burden if I wanted to host a node and limit access just to myself? Is it just a portal into the rest of the fediverse or is there a large maintenance burden or storage requirement?
Yeah, pretty big storage requirement due to the way pictrs works. Pictrs is the piece of software Lemmy relies upon to manage image storage, uploads, and most importantly: caches pictures from other instances. This takes up a HUGE amount of storage space, and there’s no official way to clear this up, see these posts I recently made: first one, second one. The solution I resorted to is renting a 1TB storage box from Hetzner for 3 euros per month, pretty sweet deal but I was kinda annoying by it. So the cheapest deal I could find costs me 6 euros per month: 3 for an Alma Linux ARM VPS from Hetzner, and 3 for that storage box. If you’re in for the fun in tinkering (I sure as hell am in), then get ready for a good time. Other than that, if your main line of reasoning is to take burden off of lemmy.world, then I think just go ahead and join another instance. Better yet: join croud funding of another instnace:)
I don’t think this is correct, the images from one instance are hosted on that instance, they don’t get copied over. What’s federated and copied over is text and references to those images (like this
). The only images that are hosted on your own Lemmy instance are the ones that you and your users upload, which sure if you have open sign ups and a bunch of people using your instance uploading images then it will become a problem very quickly, but for personal use it shouldn’t unless you’re uploading a lot of images or even videos.Just use external image hosts for posts and comments, and only use image uploads for your own profile and banner and everything should be fine (if you want extra assurance you can disable uploads in case you forget).
Nah I thought the same but then I manually checked it. In most of the image posts I see, the image URL starts with lemmy.org.il, which made me wonder whether they’re actually downloaded or it’s some kind of whacky proxy. So I downloaded some of these pics and looked for files of identical size and hash digest, and indeed they were on my disk!
It’s not a bad decision to cache pics, because it does make the experience really smooth, and I’m not complaining about it. Mastodon does this as well
Weird because I’ve checked it before and it doesn’t seem to, one notable example is that on the lemmy.zip communities I can’t see any of the images at all because something on my network or with my ISP blocks zip domains. The posts, comments and all their text gets copied over to lemmy.world but the images don’t seem to and thus they don’t display for me due to their domains being blocked.
(Alternate DNS doesn’t seem to bypass whatever they’re doing to block it, I can only connect to .zip domains through Tor or VPN).

I agree it’s definitely a good idea to create a more smooth user experience, would also eliminate the problems that I pointed out with the images not loading due to their domain being blocked.
I fallback to one of the many instances that federate with lw. Don’t get frustrated at all bro
Yup
Maybe its just the times I’m accessing but its seem better this week to me compared to the last few ones.
I don’t blame you for this, but the uptime records are incomplete at best. I’ve experienced the site being down (and confirmed with Down for Everyone or Just Me), yet status.lemmy.world showed all systems operational. As I’m writing this, status.lemmy.world is missing most data up to yesterday and dash.lemmy.world shows 16 days uptime.
I have lots of respect to you for even having these. I also remember status.lemmy.world work mostly fine some time ago. But as of right now, both uptime monitors fail to serve their purpose.
You need to hover over the status bar to see if there is any down time for that day. We can enable it to log incidents every time there is a burp, but we are still tuning alerts as we only have it create a incident when we ACK it in PagerDuty. You can always check the dashboard for up to the minute stats, as well as https://lemmy-status.org/endpoints/_lemmy-world We’ll add this info to make things clearer <3
EDIT: Added more info to our status page, thanks for the feedback Machefi!
EDIT2: Also the missing data is due to us removing and adding more specific monitors for the different infra services.
Excuse me stop being so cool, you’re raising the bar too high for everyone else thank you
Good luck, no pressure.
On your Cloudflare account, if there was a change in the CNAME/A record being proxied vs. DNS only, that could cause an issue, as Cloudflare would then strip headers off the request that your Apache/Nginx would be looking for.
If you enabled HTTP DDoS protection in your Security -> WAF tab (I think that’s where it is) that could do this too. Might be worth disabling.
Also check for any headers your HTTP load balancer might be expecting, that Cloudflare could be stripping.
Might be worth tailing the webserver logs to see what happens to requests coming in from Cloudflare.
Thanks for keeping us up to date, I don’t mind downtime personally as long as I’m aware of what’s going on
Everyone talking about the downtime including lemme and me just enjoying lemmy like never before. I’ve experienced no downtime so far
The beauty of a federated app is that I do not have to rely on lw or lemme. Use another instance and go on with my day 😃

Down for you is not the same as down. If it’s up when you aren’t using it, it’s still up
So what you’re saying is we were the ddosers all along 😹
The hack is coming from inside the instance!
Ironically true lol
Only thing that needs to be said here is: thank you for the best Lemmy instance (in my opinion) out there!
Could look into Dacentec if you need more cheap servers. I use them for my stuff. YMMV since you’re getting a hell of a lot more traffic than I am but they haven’t blocked Cloudflare on mine yet so that’s a plus. :)
Hetzner is a pretty good provider. It would be nice to stick with them if possible.
lol
Care to elaborate?
I’m a hetzner user for years and if they are bad I haven’t noticed yet.
nah lol
I brows all, never noticed as outage lol.
You guys rule. Thanks for all the hard work.
Is there anything we can do to help? Donations? Tech volunteers? Visit hosting company with a baseball bat?
deleted by creator
I imagine spreading out across instances, and having accounts in instances beyond the biggest one helps, as it reduces traffic and strain on lemmy.world and its servers.
lemmy.world still deserves support, like with donations, though helping reduce the strain is something anyone can do, albeit small, though free of charge.
