How Much Broadband Usage is Too Much?

Semprini2k asks: "I just came home from work to find a letter waiting in the old snail mail box from my Broadband ISP. It has very nice titling on it: 'Notice of Acceptable Use Policy Violations' and also has an 'Abuse Ticket Number' associated with it. Has anyone else received these from their Broadband ISPs lately? Are they being overly cautious or are they working towards throwing off any users who might possible tax their network? I am trying not to be paranoid about this, but what are other people seeing and/or doing in this situation?" The "proper" bandwidth is liable to vary by region, but it would be interesting to note usage patters of people who are getting these letters versus those who aren't.

"'Oh, no!' I think to myself, 'They think I'm a spammer!!!' But further reading sheds more light on the subject:

According to our aggregate bandwidth usage records, during December 2003 your [...ISP...] account exceeded [ISP's] bandwidth usage limitations. The activity associated with your account was more than 100 times the national median. This level of activity violates [ISP's] AUP.
"I freely admit to using a lot of bandwidth. From the day Fedora Core was released via BitTorrent I have kept an active BitTorrent session going to help others get it too. So I find this a bit of a concern.

I called their toll-free number to inquire whether I could get access to their data. No, I cannot. All I can do is try to use less bandwidth and hope I do not see any more of these letters. 2 more and my service will be terminated."

    Look through their AUP and see if what you are doing is indeed a violation. I had a warning via email several months back from my (cable) ISP which claimed I was using "above average" amounts of bandwidth even though they advertised "unlimited" when I signed up years back. I replied to the supplied human-read address saying basically "An average is made of of highs and lows, right?" to which I never had a reply or a warning since.

While I can understand the reason for bocking these ports (preventing mail abuse) -- I find the practice both deceptive and ineffective.

      It's ineffective because spammers can just run mail servers on different ports (although it may help with abuse of open relays, but many spammers are far beyond this). I have to run an instance of qmail on a weird port so my Earthlink users can connect to my mail server (long story).

I had no way of telling that the ports were blocked until after my users signed up for service. The short of it -- I'll call ISP's before telling employees that the service is supported.

      Not to get into the middle of this flamey exchange -- but I'm not sure that I agree with your argument here. It really sounds like a case of shitty financial/price modeling and a market which no mom & pop ISP should touch with a 10 foot pole. It's not your end user's fault for using the service to it's capacity. It's your company's for improper planning

      Think about it this way: When these larger companies developed their pricing models, they developed them with an assumption of a certain amount of data transferred per month. All of the big players advertised and sold unlimited use. Now, if the calculations were all based upon limited use (and their cashflow depends on limited use) -- it's the ISP's fault for not being able to provide the service they advertised.

      Sounds like either the big players fucked their calculations up, or the market is evolving. I'm guessing that the latter is probably the case. My best guess is that outliers who use more bandwidth than average were initially calculated into the total cost of bandwidth. With the evolution of the Internet, more users are using more bandwidth. The outliers are now using more bandwidth than they had initially calculated, as well as the average use increasing.

      Well -- instead of negotiating better bandwidth rates with their upstream providers (bandwidth's cheap these days), these Tier 3 ISP's (broadband operators) went into panic mode and are now fucking their users over to make ends meet. Not OK. I don't care who you are -- if you alienate your customers, you will lose them, especially with pretty thick competition (and ISP's going under left and right).

      Fortunately (for me) TWC has not done this to me yet. I'm a relatively high-bandwidth user (mainly downstream) -- I use BitTorrent, as well as other services that may not be "average", and I do not consider my usage of these services/protocols a violation of my AUP (they don't violate anything I ever signed). The day they try to pull warning letter shit on me -- I'll take 'em to small claims court and slap an injunction on their cancellation of my account. Short of that (if I am clearly violating the AUP that they just changed under me, or if/when they start closing ports), I have no problem with explaining to them why I'm dropping their service like a bad habit. I'll also explain to them that I'll ensure that they lose other business for these practices (naming some publications that I write editorials for as well as popular blogs that I post to). Then, I'll take my dollar and pay a little more for way better service (maybe not as much speed, but definitely a company who won't fuck their customers over).

      Anyway, I can't say that I don't sympathize with you. It's a tough business. But then again, why should I get screwed over because your market is shitty.

If a business is marketing a product or service that is expensive for them to provide, you can and should expect that these costs be passed on to the consumer. This is a matter of basic economics. If your local gas station has to pay $1.50/gallon for gas to sell to you, they aren't going to sell it at $1.15/gallon. Or, if they do, they won't be in business for long. Why should an ISP be any different? It seems to me as if there is an underlying mentality of "I have a right to use and abuse this connection however I want and not have to pay for it."
