we’ve recently had a site falling over when the MySQL db bugged out with “too many connections” errors - looking at the load balancer logs the origin IPs seem to be chinese but the URLs they’re requesting are all spoof domains ending in london.cloudapps.digital, does anyone know what the issue is there? why would they be spamming our load balancer for GET requests for a random domain?

comes down partly to webserver config, you can set it up so any unknown host names end up on a dummy/empty virtual host
