I've read stories about this a few times this year but this is the first time my site has been affected by AI crawlers causing downtime on a site.
My own problem was that I ended up with too many concurrent users on my database so it stopped working.
I had to move the site over to CloudFlare and rewrite a lot of the code so it caches and doesn't call the database so much, but I've got it sorted.
Has anyone else been having downtime this year because of AI crawlers?
