As a result, it can not respond to legitimate user requests as it is already preoccupied dealing with malicious traffic. This can make your website inaccessible for users, which results in downtime. Moreover, it can also negatively impact your business continuity. That is why it is important for businesses to acquire DDoS protection from a reliable service provider who has a track record of blocking DDoS attacks.
