May I suggest Prolexic?
as a previous pool operator waffle will have to choke up 1000-3000K per month for proper DDOS protection.
Cloudflare was a joke. I tried it. Prolexic, which I got a quote and never went through with, appears to be better.
Thanks for the numbers. They're actually not as high as I thought they would be, but still high enough to raise pool fees.
I have four backup pools configured, and the ones with the lower fees are generally first on my list, provided they have a good operator and a proven track record of payout per hashrate (which many people around here know I prefer to refer to as BTC/MHD!)
