This is my first post on the .co.uk site... and I've got a vaguely technical question for you all...
I work for a publishing company in Glasgow, and we have a range of sites aimed mainly at Scottish internet users -- a few newspaper sites, plus sites for Recruitment, Property and Entertainment listings.
From looking at our web stats there has always been a stable level of traffic across all ISPs on each site. For example, if a site gets 1000 user sessions a week from AOL users in August, you can guarantee it'll be within 10% of that figure for September, October, etc. The same has been true for all ISPs, including NTL, for as long as I've looked.
However, something strange happened around the weekend of November 7-10. Our user sessions (and page impressions) for NTL users dropped by about 75%, but remained static for all the other big ISPs.
My first thought is that NTL might have changed something, for example the way they run their proxies, so that a greater number of users come through under a single IP address... or maybe they've increased the amount of our content they cache?
Also, most NTL traffic seems to come via "ntli.net", but I know my home BB's reverse-lookup is xxxxx.cable.ntl.com. Is "ntli.net" where web-proxied users traffic appears from?
I doubt it's a site connectivity issue, as I have NTL BB at home and can access the sites without any problems.... so I don't think the drop in traffic is 'real'.
