Every time I try to access this community, ther’s some kind of problem with the server. If you have a look at the status page, it’s almost all orange/red.
The problem aren’t DDoS attack since the server is behind Cloudflare protection.
Admin/mods, why don’t you move this community to a different server instance?
I’m not accusing anybody, I know that maintain a server can be a challenging sometimes, I just want to enjoy this community!
Please!

But isn’t Cloudflare supposed to block those attacks?
Cloudflare DDos protection isn’t a silver bullet; the attacks are distributed and come from shifting source IPs, and are sophisticated in that they exploit resource intensive queries specifically designed to overload a Lemmy instance. If lemmy.world were to pivot to some other instance, who’s to say the culprits wouldn’t just resume their efforts pointed at the new location? There are theories these may be carried out by the recently-defederated fringe hate communities
Cloudflare has DDoS protection but it can’t stop everything 100% of the time. According to the admins, the attackers are very familiar with how lemmy works and are using this knowledge to overwhelm resources. This isn’t just a simple script kiddy or bonnet for hire but likely points to someone that has worked within the lemmy community.

From what I understand, Cloudflare can block some DDoS attacks, but not all of them.
The attacks on Lemmy have to do with poorly optimized SQL requests; these are requests that shouldn’t take long to execute, but do due to some oversight. By spamming these requests, the attackers can bring Lemmy on it’s knees.
Actually, wouldn’t this attack better be categorized as a DoS attack ? What’s so distributed about it ?
