Cloudflare Parser Bug Report (blog.cloudflare.com)
Cloudflare recently released a blog in which they announced a serious bug which may have resulted in private information being leaked and cached by search engines.

"The bug was serious because the leaked memory could contain private information and because it had been cached by search engines. "

For those that use Cloudflare (I do for my sites), you'll want to check your emails as they did email their clients. Our email said that our sites were not impacted by the data breach. You should ensure that any emails received by Cloudflare were read and that your site(s) were not impacted. 

I still recommend using Cloudflare to reduce spam hitting your server. This breach is a bad one but they did catch it quickly and took steps to repair the issue. 

Note that this post is for general website help and tips. It does not pertain specifically to SocialEngine but is just meant to be a help for our clients that might be using Cloudflare.
