Yes, I have been capped, probably one of the first group of TelkomInternet users to get cut off in 2006!?
Used total GB: 15 GB (includes both uploads and downloads)
Date/time the cap was imposed: some time over night between 06/07 January (was on a full 24 hour cycle, so it could have been judged over the limit any time through the day on the 6th I imagine).
My guess at how the TelkomInternet "management system" works (please post your thoughts if you know any better):
Although the usage e-mail says "your service may be discontinued once the average usage for all subscribers has been reached" users are probably pooled based on some form of their usage history. So for example, because I was amongst the heaviest users in Dec (probably, about 75GB), so I have probably been pooled with other "heavies/abusers/whatever" for Jan. Presumably our average has now gone well-over a prescribed limit (wonder what this is, my bet is that it is actually more than 3GB, possibly 10 GB). So all users in that pool who have now gone over their cap (3GB in my case) are now cut off. Those who haven't reached their cap yet are OK, but will probably be axed the moment they do go over (well as soon as they need to get a renewed IP address anyway).
Other people who did much less traffic in Dec will possibly be in a lower usage pool, maybe even with users who never get anywhere near their cap. So they may still be able to run up much higher numbers this month. They might find themselves in a different pool in Feb though if they go for it.
NB: This is just my guess as to how it may work, don't take this as gospel! Things I would like to know if my theory is right:
1. How big are the pools of users?
2. What is the "real" usage amount (average) at which pool members start getting hard capped?
3. How does your "history" get calculated? Will I still be pooled as an "abuser" in 3 months/years time, or will I be able to slip back into the masses if I consistently use less?
4. If I were to buy a new username would it go into the low usage pool?
You can probably see from this where my thinking is headed - if you could afford it and the "history" factor was reset quite quickly you could probably reach relatively huge numbers every month with multiple accounts - if you knew how to play the system. Not that I'm planning to. But I would be interested to see the comments of others who have been giving this some thought.
