Re: Provider-based DDoS Protection Services

[John Neiberger <jneiberger () gmail com>]

Protect thyself how? For DDoS protection to work, the nasty traffic
must be stopped before it gets to my access circuits. Once it gets
close enough for me to do anything about it directly it's too late.

The problem is that I don't know enough about DDoS traffic patterns to
make an accurate assessment of these statements, which is why I asked
the question here. I'll be doing other research on my own, of course,
but I thought I'd check here first.

Many thanks,
John
