How often are you getting DDoS'd?

The financials of using a managed service provider vs.
buy-all-your-own-grrovy-stuff can be fairly compelling especially if the
amount of DDoS you experience is almost nil.

Re: Arbor. I don't have any recent experience, but they've been around for a
long time, have a very experienced team that understands ISP and enterprise
and the product is mature. Hard to go wrong if you can justify the costs.
YMMV.

Best,
