Avoiding dDoS attacks. A study in progress

Situation: Our datacentre got hit by dDoS attacks 4 times in the last month.

Each time, our servers were unavailable to the public for over an hour, the first time even something around 5 hours.

So now I’m looking for ways to distribute our server infrastructure geographically – and also looking at cloud servers.

Our infrastructure is a mixed linux / windows environment.

First visits:

After browsing their website I’m impressed. F5 Load balancers are included in the setup and there are a lot of starting images to choose from. Another advantage seems to the price.

Things I disliked right away: All servers are located in the San Fran data centre. This means that our european customers get the high latency version of our sites.
