Hello,
My short term apartment has an iCable connection whereas all the time I spent in HK I used Now Broadband.
I've noticed some interesting differences: On speedtest.net I'm getting a substantially faster reading on iCable, but the connection is definitely heavily shaped. For big downloads download speed drops quickly.
But I have also noticed some Web sites behaving "weirdly" on iCable - which I never had on Now. And also I have noticed that I get 404 errors on any twitter url. Even twitter.com
Any iCable users able to explain this?
