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.

    Which viable alternative could work to mitigate ddos?

    Out of my head, I think OVH offers such a service (but without free tier).

      OVH is cheap but their anti-spam/abuse departments are ineffective. Too often they do not action blatant spam reports so in effect OVH is part of the problem with network abuse on the Internet. I’ve had to blackhole many of their netblocks while the people who run mxroute (solid email providers) have written about doing the same.

      OVH needs to clean up their act.

        Sure, but you still have to pay for servers to run the proxy instances on. Any DDoS of appreciable size will knock over the number of instances that lemmy.world could stand up. Interesting thought, though. Maybe CloudFlare or others use HAProxy internally? I’m actually not sure what tech they use

          It’s usually very effective unless the amount of connections is too much for one machine anyways. Along with bandwidth shaping and connection throttling it can fend off smaller attacks.
          A huge botnet would bring down a single proxy instance in any case, true.
