More NTL Stuff from http://www.adslguide.org.uk/
another statement from the ntl:home Managing Director. This statement addresses many of the questions that people have been seeking answers to over the weekend.
The main thing raised by this Q&A session appears to be the measuring period used:
3. How flexible will ntl be about these new limits?
We will be very flexible. Our objective is only to limit very frequent or persistent heavy network use that can impact other customers. Therefore we will ONLY contact customers who exceed the daily data limit for three or more days in any consecutive 14-day period.
If you occasionally exceed your data limit, it will not be a problem. Remember our goal is to give freedom and easy usage to our customers. This rule ensures that you have peace of mind and that we are able to reduce the unfair prolonged usage by a small number.
So as long as you do not exceed 1GB (Giga Byte) on 3 seperate days in a two week period, then you are fine. Interestingly this is different to allowing a 14GB limit in the 2 week period, for example a user with a 1Mbps service could download 10GB on two days, and if they stay under the 1GB limit the other days, they would stay within the limits (a total of ~31GB of data). The unfortunate user who perhaps exceeds the 1GB limit to say 1.25GB on four days but stays under 1GB for all the other days is potentially affected (a total of ~14GB). Taking the mean total download per day over the 14 day period would appear to be fairer.
The good news is that NTL are looking at the position of users on the 1Mbps service, as to whether they deserve a higher bandwidth limit. Interestingly NTLs average broadband user only consumers 100 MegaBytes of bandwidth a day
