Apache Website not loading – DDoS

On a Fresh Cpanel Server, after pointing the domain name to the server, the website won’t load. Some times site loads after a very long wait. Apache was working fine and the server load was normal.

Cpanel/WHM Apache status

On checking Apache status in WHM, I found all workers are in use

On another somewhat busy production server, I had “18 requests currently being processed, 132 idle workers”.

On checking apache error log /etc/apache2/logs/error_log, i have error related to MaxRequestWorkers

You can find the errors with the command

On checking the connection with netstat, there were a lot of incoming connections

netstat ddos

The server was getting some DDoS attacks causing the server to go down. The issue is fixed by enabling the DDoS protection service provided by the server provider.
