If you 100% sure the files are non cacheable then I suggest one of the 3 has happened.

1 - ntl proxies ignoring dont cache tag.
2 - ntl are shaping, since I did my tests before the recent changes and I think ntl are at least shaping traffic to improve pings now so may be doing same for http but I just havent tested since.
3 - their is a problem only affecting ftp throughput, sometimes things like send rwin only affect the ftp and not http and they perform different for specific reasons this may or may not be the case I dont know.

If you get a chance do those traceroute's please.
