Contact your hosting provider
In case you are unable to fix issues yourself or through your system administrator, e.g. by troubleshooting server errors, your next course of action would be to contact your hosting provider. However, depending on whether your server is located in your country or abroad, your experience with the hosting provider may differ.
Even though foreign hosting providers may provide a better service than those in your country, you should also be aware that their support might not be up to the standards in resolving the issue with your website quickly.
Hosting providers with 24/7 support are the best option nonetheless, as well as those who provide additional support channels (live chat, call) in addition to opening a support ticket or sending an email.
Activate DDoS protection
Distributed Denial of Service (DDoS) attacks , which aim 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.Error Server Site Hosting
