Site has been unusable for me intermittently for like a week or something, do we have some ideas for how we could mitigate the DDOS issue?
Are we looking for something like Cloudfare but not Cloudfare?
Increased server capacity?
Backup instances to move to when one gets overloaded?
We already sit behind the Akami DDOS prevention system. I do not think cloudflare would be any more effective.
When I look at the server - I am seeing the same behavior I saw when the big Lemmy instances started upgrading to v18. And these recent problems started when they started upgrading to release candidates for v18.3 - So I think this is a Lemmy federation problem not DDOS attacks.
We have plenty of bandwidth - do not even coming close to using it all. When we have these problems I am seeing spikes in CPU usage (normally 10% but spikes to 150% when we see these issues) and Disk I/O.
We plan upgrading the version of Lemmy we are running this weekend to see if that makes a difference.
You are a good admin
Glad to hear man. Thanks for the hard work
