It requires special infrastructure and skills.
I'm aware, I used to be a partner in a hosting company for years, I've done more than a few DDOS mitigations. :)
Most of the time we were able to shut down a DDOS ourselves but on a few occasions when it was too big for us to handle, we had some customers that were high value targets, we simply called the upstream provider (like Level3) and they took care of the problem. Sometimes resolution was just a few minutes, in a couple of really bad cases a couple of hours, but it was always resolved.
Today it doesn't require so much skill, except to install one of the many off-the-shelf hardware or software solutions or simply find hosting solutions that provide it already.
Like I said, if your host can't do it shop around, it ain't rocket science and there are lots of DDOS solutions and services currently available.
Yes, there are some basic things they can do like improving server performance but that is not the same as DDoS protection
That's not what Rackspace claims:
Rackspace DDoS Mitigation Services, also known as Preventierô, is a unique DDoS hardware-based program that ensures customer uptime in the event of a DDoS attack. No other hosting provider has combined three such disparate technologies to create such an all-encompassing protection system for their network. From network-wide packet scanning through granular traffic analysis right down to server-level anomaly detection, three layers of detection identify and filter hostile traffic 24x7x365. In effect, all DDoS processing is offloaded from your configuration to a Rackspace infrastructure allowing you to continue to do business. Our DDoS Mitigation Services allow you to choose the level of service you need at the price you want to pay.
They just didn't say it was free.
