Our experience with DOS attacks is that Varnish will happily deliver
more pages/second then the receiver can swallow.
Our uplink provider blocks the DDOS attacks.

How does Varnish handles DDOS?
I've interviewed a couple of sysadmins that have been hit with DOS and
DDOS attacks a couple of times. I've write an article that is
available for download here:

A lot of the time you can get much better results blocking stuff with
Varnish because you can block on the HTTP level, so you can block
specific user agents, accept-encoding strings or on any combination of
headers.
