Gian,
Thanks for responding. Instead of categorizing through amount of cap used why don't you simply make it 200GB international, completely uncapped and unthrottled local (Most people that perform heavy downloads are happy with local only bandwidth) and then rate limit to 384KBps once they hit the 200GB. Judging from the comments in the other forum topic it has become evident that MOST would be happy to have access to 120 to 200GB (mostly sub 120GB of avg usage was mentioned) You could even do the same as Mweb and shape certain ports dramatically during the day and ease up on the shaping at night) This will leave time for work and play as there are very few people who use their internet connections purely for play. Some of us really do NOT want to leave Afrihost and personally I do believe this is all manageable. As long as the right expectation is set as you have done above and communicated thoroughly.
I know for myself that I have averaged between 100 and 120GB per month for the last year. Of this estimated usage for personal (streaming youtube, gaming, episodes etc) have made up only about 20 to 25% of my total traffic. Some of the more heavy users are generally in IT related jobs and the more you support their needs the more they will support you. By word of mouth advertising and such you will increase your revenue. Ask any IT person regardless of the role he performs how many times he has been asked the question (which ISP should I use and what package should I get). We always get asked (because we are in IT)
Just a thought - use it don't use it.
P.S. I have worked for an institution where we had to limit traffic use significantly. If you would like to know the measures that we used to fully utilize our bandwidth while keeping everyone happy you are welcome to PM me and I will answer any questions you have.
This won't work, once you impose a limit the user will have a "target" to hit, how many times with our old capped accounts havent we all just downloaded at the end of the month to make sure we finish our bandwidth we paid for?
