Does anyone know why Lemmy.world has been unstable for the past two weeks?

In the past two weeks, the site has been very unstable, sometimes for one second a page would load and the next it wouldn’t load at all. The status of lemmy.world would fluctuate a lot on lemmy-status.org, and there have times where the site has been down for hours.

It’s been under attack from malicious actors, some DDoS, some database related (they overload the database with download requests). Likely because lemmy.world is one of the largest instances and they figure they can cause the most damage by attacking this one.

DDOS attacks

Didn’t they also say that there were other kinds of attacks being used as well, not just DDoS I may be remembering wrong but I feel like I heard one of the admins say something about a database related attack where they overloaded the database with download requests or something like that.

Could be, I’ll look into that

Either the problems with its API responses are breaking lemmy.world, or a broken lemmy.world is causing problematic API responses.

Currently, you can ask lemmy.world for page number billion of its communities and it’ll return a response (for the communities it thinks it has on that page, rather than an empty one, as it should). For something like lemmyverse.net, this means its crawler can never get to end of a scan, and some apps are maybe trying to endlessly load the list.

TheTwelveYearOld OP ,

Can you check periodically so you can get the link?

freamon ,

Yep. Worked this time, so I’ve edited my comment.

Oh wow, I thought this was a bug in the Lemmy api. I was implementing comments paging in my app the other day and noticed it would just infinity load pages with duplicate comments. I guess I should have tested with another instance before disabling the feature.

There have been numerous ddos attacks etc on the site recently. Rudd, the operator has been very forthcoming with information.

TheTwelveYearOld OP ,

Where can I find this information?

I would guess that its due to the rapidly rising number of Users.

schwimmbux ,

Ok, who’s attacking?

…which stem from the large userbase making it an attractive target.
