CloudFlare is probably not a good choice. They recently blocked access to a similar service, Lantern, per the linked WSJ article.
"CloudFlare, which offers content-delivery network services, said last week it cut off Lantern’s use of the service, saying it was unauthorized. “We don’t do anything to thwart the content restrictions in China or other countries,” said Matthew Prince, chief executive of CloudFlare. “We’re a tech company and we comply with the law.”"

I'm not very impressed. Maybe someone from CloudFlare is around to defend that position further.
