Lemmy.world update: Downtime today / Cloudflare (lemmy.world)

Today, like the past few days, we have had some downtime. Apparently some script kids are enjoying themselves by targeting our server (and others). Sorry for the inconvenience.

Most of these 'attacks' are targeted at the database, but some are more ddos-like and can be mitigated by using a CDN. Some other Lemmy servers are using Cloudflare, so we know that works. Therefore we have chosen Cloudflare as CDN / DDOS protection platform for now. We will look into other options, but we needed something to be implemented asap.

For the other attacks, we are using them to investigate and implement measures like rate limiting etc.

Well I signed today and I got an error saying rate limit earlier for using these types of symbols "î¦âö)ééäë((ºÜݨ¿ã¿ï" I'm assuming It has nothing to do with this but just In case I'm making a comment about it edit:also just realized It may have been from how long the password was (33 characters)

This might be related. Encrypting passwords is resource intensive, and longer passwords need more resources.

Specifying really long passwords, repeatedly, is one way to DDoS a server. Maybe they're blocking unnecessarily long passwords.
