DDoS (distributed denial-of-service) attacks are a common cause of spikes in website traffic connected with malicious bot activity. This is when the attacker uses a collection of different servers across the world to send traffic to the server over and over again until it can’t handle the load and crashes.
If a website has been hacked, it means someone has managed to gain unauthorised access to a server and its data. This is usually done using a virus (malware or trojan), often through an un-patched loophole in an outdated WordPress plugin.
A DDoS attack is not the same as being hacked. The attacker is usually unable to gain access to the server or any secure data from the database.
We also deploy an additional firewall that sits between the domain name and server, allowing it to intercept any attacks before they are even able reach the server. If you suspect that your site is under attack, please contact a member of the development team.
