What are DDoS attacks and why do they happen?
In short, a DDoS or Denial-of-service attack is a large scale of fake traffic that is sent to a website in an attempt to weaken its host server until it fails to work properly.
The most common reasons for DDoS attacks are these:
Your competitor wants to attack your website to harm your business and prevent you from making sales and serving your customers
Hackers may attack your website to extract important personal and business data
Attack targeted to one or many other businesses as with Shared Hosting, IP is shared with other people and you will be affected if you’re on the same server
How to spot and prevent DDoS attacks?
A good indication of a possible DDoS attack is a suddenly increased amount of requests, which can be checked in your Order Usage section under the Total Requests tab:
In case you are seeing a requests’ amount growing exponentially and you weren’t expecting that much traffic, it’s highly recommended to change Cloudflare Security level to Under Attack Mode. This will ensure that the majority of these fake requests will be rejected by Cloudflare.
However, sometimes DDoS attacks can be so big, that we are forced to null route your hosting IP, which deems all websites on this server unavailable. Usually, DDoS attacks last no longer than just a few hours. In case you don’t want to wait until your IP becomes available again, you can consider a server transfer.
You can perform server transfer once per month
Another prevention tools are Cloud or VPS Hosting. With these, we provide you with dedicated IPs which are less prone to DDoS attacks, although they can still happen if attackers get a hold of your IP.
