Ok, maybe I should have stated what's useful to help me find the root cause rather than people telling me things like BT are a major ISP, or unnecessary tracert/ping results. I do appreciate the effort though. So please let me know if you get blocked, what you are blocked from (the whole site, certain links, posting messages, PMs etc), what you see when you're blocked (a screenshot would be lovely), your IP address (both what's on the screen and by typing in 'what's my ip' to Google) and the time it happens. The more I get the more useful it is. Unless you were affected please don't tell me you access is ok. @edhistory, I suggest you contact Cloudflare and ask them, but you really don't need to be paranoid about them, they help the forum run.
