How could they not anticipate the storage needed? Take the number of accounts that had 2 megs and add 250 to that, and then figure in the projected growth for a however long. Not really that difficult..
I can just see some bureaucrat using this as proof to cut funding from the space program. No need to invest in landing gear, just let it crash.:) But seriously that's a testimate to how well they build and designed it.
I've recently developed several cable modem network applications that run off a Sparc box loaded with Debian with PHP and mySQL. They connect into the cisco 7200 and 10k series uBR chassis and allow our field techs to resolve the hybrid fiber coaxial mac address on the modem to it's internal 10.x.x.x ip address. This allows them to pull snmp data from the modem, such as RF levels, bandwidth, errors, etc.
Now getting back to the topic, the reason I went with Debian is that it allows me to easily install what I need knowing that it's going to work without any trouble. I can dedicate my time to development rather than trying to figure out why line 5234 in blah.h is giving me some error. Incidently, the combination of my software and my Debian server got me a presentation in front of the company president. That's really saying something when there's 16,000 employees. As a side note if there's interest I'm considering creating a sourceforge project for my work (assuming it gets approval from my boss.)
I checked the site out and to me this is simply a spreadsheet that automatically graphs the data. I'm sure you could write an excel macro that would do the same thing.
My very 1st machine was an Acer 486/66 dx2 with 4 megs of ram and a 500 gig hd. I was about 12 at the time and the king of Dos:). Is it just me or were the games back then a lot more fun than they are now? I remember playing Doom, Leisure Suit larries, crystal caves, etc.
Linux can already compete with Cisco IOS in most routing functions and with the correct hardware you can pretty much match most of their routers. Cisco hardware is insanely overpriced, a stick of ram can run you 2000$ when someone elses would be about $50. But when your in a big business you need the support contracts so when IOS goes ape shit you can have a few cisco engineers track down the bug.
Since you say that reliability is your top priority I'd recommend a dedicated VOIP service provided by a cable company if available. They are required to offer the same level of service as a phone company, and also included life line support. While Vonage, Packet8, and the like are all excellent services, they are only as good and as reliable as your existing internet connection.
I am a major cable company network engineer... and while the idea of allowing certain people access to having the ports open is nice in theory, it would be nearly impossible to implement on a large scale operation. With existing infrastructure all restrictions are placed in the access control list on the CMTS router. Without purchasing additional firewall equipment that can service a 1/2 million customers, which would run upwards of hundreds of thousands of dollars. The only way to selectively allow individual ip addresses to be able to use outbond would be to have individual allow statements for each customer who requested it placed on the ACL. Since nobody but the network group is allowed access to these systems we would need individual people dedicated to simply adding ip addresses to the ACL. And of course since each time a packet on port 25 is sent the entire outbound port 25 ACL is processed the load on the routers would be so high that additonal upgrades would be necessary.
The entire reason to block all outbound port 25 connections is to stop those with viruses/spam relays from causing the isp's email server from ending up on blacklists from the likes of AOL, earthlink, and other very large isps.
So the trade off is you inconvince those customer's who are already violating the acceptable use policy by running a prohibited email server or force them to use your outgoing smtp server. In the end the vast majority of customers are much happier because their email works better, has less spam and garbage and the isp has less work to do by contacting and disabling the service of those customer's spreading viruses or spam via email.
If your the type that needs a service that allows servers, static ips, 4 hour service resolutions, higher upload then you can pay extra for those things and get a business class connection.
That's really what it boils down to.
There's a million and a 1/2 reasons why they would keep your info in their database. Let me give just a couple examples.
1.) What if you at one time had their cable modem service and they provided you with a cable modem. Upon disconnecting service you never returned it, and tried to either re-register with your name or someone else's name at a later time. Or you sold it at a rummage sale. When you or the person that now has it tries to re-activate the service they will see that the modem was last on you account, and that it's owned by them and they will want it back or to charge a fee for it or call the cops on you/them.
2.)
Let's say that you had service with them at one time and that you are claiming 2 years later that their tech support damaged your computer and try to take them to court. They would have all records of the contact you made with their technical support staff and could use that to defend theirselves.
If you want to know the honest to goodness answer, every customer a company has is a liability in one way or the other and the company needs to do everything they can to protect theirselves.
but my company runs Websense on our system to prevent looking at specific stuff that may not be work related. They also block access to the free html proxy servers online so you can't do that.
Here's my solution: Run sshd on a machine, in my case Debian Linux. Install apache and also CGI Proxy on the same machine. Using Putty or the ssh client of your choice create a tunnel for port 80, and then access your site via http://localhost/cgi-bin/nph-proxy.cgi and you will be able to proxy securely and anonymously.
In order to provide per channel service with existing HFC (Hybrid Fiber Coaxial) systems, the content would need to be delivered through digital as the analog way of blocking and allowing channels to put a trap on the line that filter out the frequencies that contain the other channels. Basically, without going to digital you would need a filter for each individual channel, which isn't feasible for various reasons.
I think ~$7 per channel because I'm assuming the subscription rates from companies like Viacom will go up.
If your are going to require cable companies to provide any channel ala carte then you need to require any competing company to do the same (Dish systems). It's the content providers that force the MSO's to bundle channels that 95% of the subscribers will never watch.
On top of all this I would expect it to be pricey to get an indivdual channel, ~7$. The entire cable network would be forced to upgrade to digital which would cost millions, and all your tv's would require a digital box.
And if your wondering, I'm a net admin for a major cable company.
I spoke with a customer who got emailed the message "Is it true?" and the attachment nakedpicsofyou.zip and they immediately opened because they thought someone took their picture through the monitor.
I swear to god this is why turning off peoples internet for having a virus needs to be done. 98% of the PC users only know something is wrong when either A.) the mouse pointer won't go or B.) They can't check their email.

Yeah that should be a 500 Meg hd. My bad.

Cable Voip has the same levels of reliability that POTS has. Thats the requirement for offering it along with 911 calling.

Funniest damn thing I've read since Sasser.
I'd be too embarrased to admit that I know these people. It makes playing D&D look cool.

Is this story a troll?

Regardless of your sex, if you take offense to being called a geek you shouldn't be posting on slashdot.

I know for a fact that other broadband companies do this. Viruses create all kinds of problems with the routers since they create a lot more traffic.
I immediately thought that the topic was refering to the average grocery store shelf-life of a can of spam.
Ok so it's not funny.
