DDoS is a hosting provider nightmare. So does for a webmaster. If there is a DDoS, tools like Cloudflare helps you deal with it. If I remember correctly, Succuri has some tool for it too.

Other than that, some downtime is almost certain if you are not walled well against DDoS.

The best way to avoid DDOS attacks it is to contact your host, if you are located in datacenter, I would contact technical support of the datacenter. They have responsibility to keep your site running on. I don't personally know how to avoid, but myself I was under ddoss attack from a while and I contacted my host and after one week it ended. I got also mail from my hosting company and they said, that they had contacted FBI technical apartament for abussing their service. I think big datacenters have power, so don't hestitate to contact them.

A distributed denial-of-service (DDoS) attack is a malicious attempt to disrupt normal traffic of a targeted server, service or network by overwhelming the target or its surrounding infrastructure with a flood of Internet traffic. DDoS attacks achieve effectiveness by utilizing multiple compromised computer systems as sources of attack traffic. Exploited machines can include computers and other networked resources such as IoT devices. From a high level, a DDoS attack is like a traffic jam clogging up with highway, preventing regular traffic from arriving at its desired destination.
