Indeed. The problem in many cases was scaleability. The ISPs used a cacheing proxy to cut down on their backbone traffic but the proxy solution wasn't really scalable and in the end the proxy degraded customer experience instead of improving.

So one of my concerns is how the Phorm proxy will scale. Last summer I'm 100% sure I was caught in the trial, my connection was AWFUL but I was busy with a project and the only analysis I did was an ethernet trace and I only looked at L4 which was problematic because of duplicate TCP ACKs and out-of-sequence traffic. I worked around the problem by re-routing all domestic traffic via my office gateway.

Oh - and to complete a tale about proxies in general, in the last few years backbone capacity has increased whilst backhaul has become more contentious so it never really made sense to develop better, more scalable proxies. Also a lot of dynamic web content sets no-cache and cache expired so caching these days helps a bit on images but that's about all.
