DDoS
An attack that drowns a site under a flood of connections to make it unreachable.
A DDoS attack overwhelms a site or service with enormous traffic, until it goes down and no one can use it any more. That traffic comes from very many hacked machines around the world. You protect against it with services able to absorb or filter this deluge.
