Anyone running a webserver would agree, security can be a hustle and tedious job. Recently I came across a service claiming to help with that -- CloudFlare.com. There's plenty of benefits listed on CloudFlare's own website, however I'm interested if there are any potential drawbacks switching your DNS to theirs. A few blog comments had some cautious remarks about CF's system being too aggressive and flagging even site owners.
Aren't there any benefits in having your own name servers, perhaps from SEO stand point?
Also they talk about caching content on multiple servers... What if your content is not static?
Trying to get as much info as possible before making a decision. Any insight would be highly appreciated.
