Almost all major broadband service providers have a fair use policy for domestic customers. IN the three cases given below, only tiscali has a limit of 100 GB per month. Others are evasive. But all are talking about only a small % of users - less than 0.5%.
It is better to fight for a big increase in download limit than no-fup.
TISCALI
A very small number of customers use an excessive amount of the network bandwidth at peak times, to the extent that it can impair the performance of others. Tiscali's Fair Usage Policy is designed to provide the most effective service to all Customers.
Only customers downloading well in excess of 100GB a month are likely to be impacted by the Fair Usage Policy.
This is the equivalent of downloading more than ten movies a week, or watching streaming content for more than 6 hours every day
The Fair Usage Policy will adversely impact less than 0.5% of the users on the network.
BT
A very small number of our customers use their broadband service inappropriately, for example when sending or downloading very large files, or using 'peer to peer' and file sharing software (which may be sending and receiving video and other large files constantly). This means that service quality for all users is affected, making it slower for everyone to access the internet or send and receive emails, especially at peak times. Peak times may fluctuate between 5pm and midnight, Monday to Sunday.
AOL
This is necessary because excessive bandwidth usage (exceeding what we deem to be reasonable usage levels for a residential broadband product) slows down our service and affects the online experience of all other AOL Broadband Members. A small minority of members are engaging in substantial continuous download activity of a level that is not the norm for a residential service. The Fair Use Policy has been put in place to ensure that there is optimal service for all members. We monitor network capacity and usage accordingly.
