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.
just to add to this, I was wondering why I noticed lemmy.world was now causing my ublock origin and privacy badger to flag me with a cloudflare tracker when there wasn’t one before, and I found this post. every other instance I frequent doesn’t show a single tracker
edit: didn’t want to leave the instances as ambiguous - the instances I go to that don’t show as having any trackers as of the time of this comment: lemmy.ml, lemmy.dbzer0.com, lemm.ee, and lemmy.one
