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!)
The price really does matter on how many different IPs he wishes to protect and any other custom services.
The more regional servers you have the more it will cost. But once again Prolexic offers quotes based on what
the customer wants and you can dicker with them a bit. Essentially 1200 dollars for an IP or two is what it will
take money wise to get your foot in the door. 3-5 regional servers? double/triple it.
