It's very odd, nothing has changed this end. I will do some log digging. Every access to the website is logged. As you can imagine these logs would be use. Each day is a separate log. Eack item that creats the webpage like sale sheets, images, is on the log. So could be say 50rewiests for one page.
What is the error it comes up with? Is it 'nginx gateway'
If you are not logged onto the forum can you view it?
Can you both view
www.our-bailey.co.uk at the same time?
These tests will help narrow it down. 'Our bailey' is on the same server do has all the same firewall walls, I wonder if some force attack has enabled a lock down in an area. If so then you would get the same issue on any website on the same server.
I may have to get the chap at work to bring in his iPad and macbook and see if I can get it to fail there. Viewing the website on multiple PC's, PlayStation and mobiles from the same internet connection all works fine.
It's an odd issue that would be nice to get to the bottom of.
