Don't know for sure as mine is not specified it's on auto try any of these. I only know I'm Leicester because I use the connection tab at the top of the page. The problem could be local to you as it's ok ere in Chellaston.

Leicester 1 = leic-cache-1.server.ntli.net
Leicester 2 = leic-cache-2.server.ntli.net
Leicester 3 = leic-cache-3.server.ntli.net
Leicester 4 = leic-cache-4.server.ntli.net
Leicester 5 = leic-cache-5.server.ntli.net
Leicester 6 = leic-cache-6.server.ntli.net
Leicester 7 = leic-cache-7.server.ntli.net

Just ran the check and we are both on the same proxy???
Results:

You are using the 'leic-cache-7.server.ntli.net' proxy server.

This is an ntl Proxy Server in the Leicester area.
