Hi all,
I operate all the TGC web services, so am best qualified to put your minds at rest on this one.
We do use CloudFlare for some of our services, however we are not one of the affected CloudFlare customers. None of our traffic has been leaked and your credentials are safe.
If you wish you can of course reset your passwords to have that piece of mind.
Overall the CloudFlare issue has been extremely over exaggerated by many. The tiny amount of requests and the unlikelihood of any sensitive data even being contained with the requests that did get leaked, means this is quite a low level issue. Most of the talk around this is coming from those who don't like CloudFlare as a service and have a reason to hype up the issue.
