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.

Excellent! CDN and DDoS protection are essential. Also would recommend looking into load balancing if you haven’t.

Load balancing applications is significantly more complex than most people anticipate. In the naive implementation it typically increases database loads and reduces site performance. Static content balancing is trivial, and cloudflare will do that by default, but implementing the hard part will require careful software development to prevent a naive implementation from bringing down the database. Sticky sessions are just the beginning.
