Firstly, please don't move this to help, I'm not asking for help, this is a bug report.
So, I'm trying to use a landline broadband connection to browse the giffgaff site, and every page I try times out, and I get the "check your connection" message.
Every other site I've tried loads without issue.
I've used 2 different devices, and it's the same scenario.
Connected to my giffgaff data and everything is fine.
It's as if the ip has been blocked or something.
It's eclipse broadband, delivered via a landline.
Obviously I could just use my giffgaff connection, but then I'm using my precious data, when I could be using a perfectly good unmetered connection.
Also this means that if I had this issue and wanted to browse giffgaff, activate a sim, top up a dumb phone etc. & didn't have an alternative way to connect I'd be out of luck.
I'm wondering if something is being used to block spam etc, and it's acting too aggressively, producing false positives.
