Comcast has a 250GB cap per calendar month for transfers made over their home cable modem services. They claim that this meets the needs of 90% or so of their users and that the other 10% is damaging the network. Perhaps this was true for 2009, but I don’t feel that it is true for 2010 or the needs in the future.
What is this Cap? I thought it was unlimited?
Having a bandwidth cap means that you can only download a certain amount per month before Comcast gets upset. The amount is currently 250Gb and has been unchanged since they initially instituted it in 2008. Comcast does often advertise that their service offers unlimited usage, however this simply isn’t the case.
250GB ought to be enough for anybody
Just as the quote often misattributed to Bill Gates of,”640K ought to be enough for anybody.” shows faulty logic, so does the cap imposed by Comcast. Perhaps this best describes their ideal user who pays for their service, but rarely uses it. This probably does reflect a large portion of the population. My mother does little more than check her email and Facebook with her cable modem.
Yet for a small but strong portion of the population this is simply insufficient. Those between 14-34 are using the internet in a far different way than an older generation. I am one of these.
Common Uses
Everything is streaming. We live in households with several roommates who are all similarly connected. We have not once computer, but multiple. Even if our needs are currently met, we are always pushing the edge and using more and more services. A quick look at some of the bandwidth heavy services that those of this generation use.
- NetFlix- My household has all but stopped using our physical Netflix movies. Waiting a day is too long. Instead we use their streaming service, often watching several films in one night between all of the house residents. NetFlix is soon to start streaming along with 5.1 Surround Sound. 1080p which will use 2x as much bandwidth as the current 720p library is surely also just around the corner
- Hulu- Another video streaming service, which also streams in 720p.
- YouTube, Vimeo and Blip.tv- Streaming HD video content over the web has become daily activity for many people. While a few years ago this was a very small portion of people’s behavior, this is only increasing.
- Bittorrent/Usenet- Not that I would ever admit to downloading something that isn’t public domain, but I’ve heard that downloading 1080p movies with full surround sound in Bluray quality takes around 10-30GB per movie. Queuing up a dozen or so of these is trivial and commonplace these days.
- Large downloads- I recently reinstalled my laptop and I must have downloaded at least another 15GB of legitimate applications to get it up and running again as I like it. Lets say there’s a new operating system release and you do this to 8 computers in a household. Boom, 120GB used.
- Streaming Music- Pandora is constantly streaming high quality audio to the house, if not several streaming in parallel.
- Rich websites- Websites now are larger and more complex than ever. I shudder to think about using Facebook through 14,400 baud modem which was commonplace 10 years ago in many households.
- Backup services- If you’re using something like Mozy to backup your entire computer and you multiply this by 8 or so, then you’ve got a problem with Comcast suddenly. Yes, the backup (after the initial) should only do diffs, but still the initial usage is a problem.
- Professional use- I work from home often. VMWare images, Photoshop files, huge amounts of code, video, logs, Skype calls and audio go over my connection daily. This has got to add up.
- Gaming- Xbox, Playstation and PC games eat bandwidth as well from gameplay but also patches, downloads and voice chat.
I do think that a single individual would have to try pretty hard to use up 250GB/month, but a common household in the Cambridge/Boston area of 20-something tech professionals can tear through it like we can a keg. A typical evening might be something like this:
- Roommate A is watching Lost streaming from Hulu in HD in their bedroom.
- Roommate B is downloading software updates on their computer
- Roommate C is downloading some public domain/open source torrents
- Roommate D is chatting on Skype video and playing WoW
- Roommate E is playing the Xbox 360
- The Playstation 3 is Folding
- 6+ smart phones are connected and doing their thing
8 Computers?
That number is actually low. We’ve got 6 fulltime people living in my house. Add in three significant others that are often here, and the fact that most of us have more than one computer or computer-like device and we’ve actually got around 20 devices on the network. When we’ve had friends over we’ve probably hit near 50-60 devices on the network before counting everyone’s iPhones and laptops. Game systems, netbooks, an OLPC, iPhones, security cameras, sometimes some servers and a ton of laptops. It all counts.
250GB Cap Workaround
From what I understand you can’t ask them to upgrade your 250GB home package to something higher. They’ll give you faster packages so you can burn through it faster, but not bigger. You can’t buy two packages either and load balance in a single household. But there is a workaround, although I haven’t tried it.
If you call and order a small business package, it will cost you a bit more, but they won’t bug you about needing cable TV and the top speed of the package isn’t as high- but you are free of bandwidth caps.
Moving to the Future
While I don’t have any hard numbers on this, I feel that I use approximately 2x as much bandwidth online every year as I did the prior year. This has been a fairly consistent path for the past 15 years that I’ve been online. My usage goes up, but so does the complexity of the content that I’m downloading. With upcoming services like OnLive that promise 1080p gaming streaming into your household, more HD streaming, the release of 2K/4K video to the consumer market, more connected devices and greater cloud computing this problem isn’t going away.
I realize that Comcast needs to protect themselves, but it isn’t like they are on the edge of profitability. They are massively profitable in fact. Yet, they should also realize that this is a system and market that is quickly growing and will continue to do so. Equipment is getting faster and cheaper too so the upgrades shouldn’t be too painful to keep up with the curve. 2011, we will need 500GB/month and in 2012 we will need at least 1TB/month of transfer available.
