I’m in the same boat as kieran.hill1796.
I’ve been a customer of Cloudflare myself for years, so I know exactly what it is that they do. With no activity on my network here at home, over night my IP got blocked. While my ISP does have dynamic IP addresses, they are typically relatively long leases and I’ve been on this IP for a while now.
And to add oil to the fire, kieran.hill1796 is correct in that the captcha for the support page prevents you from getting there unless you’re logged in already. Even when you’re logged in and submit a ticket (which I did from my customer account), the Zendesk URL for your ticket then also presents you with a captcha, which can’t be resolved. It’s an endless loop.
I suspect that there’s been some kind of mixup on Cloudflare’s end, resulting in blocking a batch of IP addresses incorrectly. I’m seeing more reports around the internet of people being blocked out of the blue.
And to @kieran.hill1796: Cloudflare haven’t accessed your IP, it’s the other way around. They offer a service that sits in between you and the servers behind websites, acting as many things, but above all as a firewall and DDoS protection. Those sites you’ve been using for years most likely have also been using CF for years, you just never noticed before because you weren’t blocked. By using these sites, your IP address is visible to CF and these sites (that’s just how the internet works ). Unfortunately there’s very little you can do right now, but like I said I’ve submitted a ticket using one of my customer accounts to see what’s going on. I’ll post an update here once I get one from them.
