Has Cloudflare had an effect on DDOS attacks at all? I'm guessing there's been a few attempts since it was introduced, but we haven't noticed. I haven't used cloudflare, but I assume they let you know if there is an unusual amount of traffic happening?
I'm still finding the site a little sluggish, but not running into any errors or anything.
The main effect it has is that it can be adjusted to deal with an attack a lot easier than if you have your own custom system. It just saves a lot of work.
