Activate DDoS protection

Distributed Denial of Service (DDoS) attacks, which aims to “flood” the server with a large number of automated access requests, usually coming from thousands of IP addresses, in order to make the site unavailable. To prevent your site from being disabled due to a DDoS attack, you should activate DDoS protection

The most common DDoS protection service provider is Cloudflare, which offers free plans but with limited options, but there are others such as Deflect, whose services are used by many media, environmental and human rights organisations. Google also offers free DDoS protection through Project Shield, which is intended for news, human rights and election monitoring sites.
