Back on topic 
At the peak there were more than 450 concurrent attacks by my reckoning. e.g. 466 different IPs involved.
We are now down to about 50, which is a drop the the 120-150 or so that were hitting us until just a few minutes ago.

Can you not kill the DDOS attack at the router level?

Does not work like that with the servers.
We can to some degree firewall at the actual server.

Jema, can I ask exactly what happens during an attack? I don't understand at all.

When you visit a web page you browser send requests to the server hosting the website for the web files. Web servers are used to dealing with reasonably large number of site visitors without any undue problems.
However, there are some instances when a server, or a single web site, is the target for an atttack. It would be difficult for a single user, you for instance, to generate enough requests to slow down a server. So the attacker uses a distributed network of infected machines (users PC's) to do that job for them.
It can be very nasty if the attack is large and prolonged. Some high profiles sites have been down for days during such an attack.

So what causes it. Does some malicious person decide they are going to attack DS, or is it random?

Most are deliberate attacks, but others can be random.
The reasons are varied:
* Cyber warfare between opposing groups of malicious coders proving how good they are
* Criminal gangs disrupting system for personal gain
* Intercountry cyber warfare (I'm not sure this has ever been proven)
* Competitors
* Because they can
* Have a grudge
and a host of other reasons.

You never know quite what, I do know that over the last few weeks I discovered some extremely nasty forums on the free forums system and killed them off, so may be that has provoked something

Well over two hours now since anything got as far as hitting the web server.
This was not to be clear an attack on downsizer.net, but an attack on the server we are on.
With servers you have two choices, we could be on my little UK based Trillian server that is cheap and cheerful and by virtue of doing little aside from downsizer.net might even be faster most of the time.
Or we can be on one of my very powerful servers along with a lot of other things and risk being caught up in attacks against the server itself or sites other than downsizer.net.
You might think it obvious to go with the little server, but with a little server if an attack does take place, or even if something suddenly proves especially popular on the site, then the small server struggles a lot more badly. Everything about the big server from the hardware to the support is better geared to dealing with trouble when it arises.
