Web Censorship on the University Campus?

Censored Prof asks: "I teach at a private university in San Antonio, TX. Besides some horrendous bandwidth issues, we have lately been subjected to Lightspeed and/or Websense blocking. This means that suddenly, university students are unable to see content that the rest of the (free) world sees; and more importantly are often blocked from very legitimate information crucial to their area of study. Papers like Village Voice are blocked. Anatomy sites are blocked. Electronic Art sites are blocked. Anything with ".mp3" is blocked. Our CIO has assured us that this is not uncommon and that there are good reasons to do this on a university campus. It strikes me as odd that students must leave campus to learn, and smacks of censorship in horrible ways. So my question: Is this unique to our university? Who else at what other universities are subject to similar web-content blocking? Are we alone, or part of a disturbing trend?"

But no, this isn't common at all, at least at public universities (and most larger private/research institutions). In residential housing, sometimes traffic shaping and bandwidth limits [wisc.edu] are used to try to curb/dissuade inappropriate usage (and even then, nothing is blocked, and services like iTunes Music Store are added to unlimited use categories)[1], but most universities, especially public research universities, see non-censorship of network traffic and protocols as a matter of academic freedom, and a critical one at that.
Even during the heyday of Napster [wisc.edu], the University of Wisconsin - Madison, for example, made a critical decision, and decided not to censor or limit network traffic based on protocol, port, application, or tool. We viewed the increase in traffic as part of the "cost of doing business" as an academic institution, and viewed censorship of protocols or ports as a slippery slope that was an affront to academic interests.
[1] Some people still might say that's a form of "censorship". I can assure you it's not. When no limits are in place, people use services that can use port 80 and/or tunnel traffic in SSH, and a very small number of users can saturate the network for everyone else. Packet/traffic shaping equipment cannot keep up with the number of flows, so a common practice at large schools with several thousand residents in university-owned housing is bandwidth limits. Anyone can get an exception for acceptable purposes. Remember, this applies ONLY to housing; residents are still expected to follow acceptable use policies for the network that make it accessible and usable by all. Further, these are separate judgments made by the housing divisions at most schools.

I don't know if your CIO is full of it or not, but I suspect he is being less than forthcoming about things. Has he/she elaborated on just what "good reasons" there are to perform this degree of censorship in an institution supposedly devoted to learning? Who gets to be the arbiter of acceptable content? In many countries and even communities here in the US, people go to colleges and universities to be challenged intellectually and get away from censorship or limited thinking.
I cannot give you a statistical breakdown of multiple universities, but having been to a couple and being a professor here at the University of Utah, I can give you some idea for how open and flexible our campus computer networks are. We do not, to my knowledge block any sites, there is no censorship, we are able to host websites from university servers or our own servers (including blogs [utah.edu]) using university bandwidth so long as we are not hosting illegal content or using the sites for commercial benefit.
It is a very open policy here that fosters student and faculty growth and communication with the rest of the world. Granted, there will always be some problems and some abusers of the system, but I would say the benefits outweigh the costs/risks associated with Internet access.
Finally, it should be noted that as content is developed and encoded for digital distribution, common (open) formats are going to become more common. College/university courses on mp3, mp4 and Quicktime (proprietary) are becoming more common. Documents, dissertations and journals are in pdf formats, so what's their solution to this?
Re:Narrow thinking (Score:4, Insightful)
I would like to say that QuickTime, while proprietary, is often a reasonable tool to use to generate and view content that utilizes open international standards (such as MPEG-4 and H.264). Part of that thinking went into this IP video delivery project [wisc.edu] for us (more reasoning in a recent presentation here [wisc.edu]), and ultimately, QuickTime allowed us to do things with open standards and protocols that Windows Media, Real, and VideoFurnace simply couldn't, and at a cost that was (and still is) much, much less than dedicated industrial video encoders and other equipment.

It was our opinion that by choosing to actually censor internet access, a college could become responsible for the actions of its students on the net, because it shows that they are monitoring the students' behavior and choosing to intervene. Failure to "correctly" intervene could make a school liable. Establishing a policy that the school is an ISP and provides uncensored access to students who are responsible for their own actions could prevent liability for the school.

Art Class (Score:5, Funny)
As an art major in college roughly ten years ago, we ran into some problems when the I.T. department installed Novell's Border Manager software to filter naughty HTTP traffic. Whenever you went to look at, say, Hieronymus Bosch's The Garden of Earthly Delights [ibiblio.org], you would instead be presented with an obtuse Border Manager error page stating that you were restricted from viewing that web page.
Now, art history classes typically involve sitting in a dark lecture room and viewing hundreds of slides of artwork while a professor (or TA) talks about them in excrutiating detail. As you might expect, a lot of this artwork involved nudity in some way. So the obvious answer to this situation was to take a screen shot of the Border Manager error page, turn it into some slides, and slip them into the slide reel when the professor wasn't looking: "The next image [click] is Botticelli's famous Birth of Venus [artchive.com], which... what the hell?"
I suggest you try this yourself if your art history professor still uses slides. It will be funny at least once.

In almost every case I've been involved in, it broke down to exactly how crucial the information was. In my realm, if I think there's any educational value there whatsoever, I'll unblock it. I'm more concerned about proper student education then sensless content blocking. You place may be different.
Village Voice and anatomy sites may be being blocked because of overzealous regex filters. I can't imagine why electronic art (how ambigious is that?!) sites are blocked unless you're refering to Electronic Arts [ea.com], in which case I might not see your case. As far as MP3s, I, too, block any MP3 downloads at my campuses, unless requested on an individual basis for a good reason. I have yet to find a good reason why unfettered MP3 downloading aides education. Do you have one?
Now it's obvious you're biased, trolling, or just whining. Not to mention you just labeled yourself and your fellow faculty incapable of teaching without unfiltered internet access.
I don't know. Do you enjoy beating your wife?
Look, at my campuses I use a web proxy (Squid) for several reasons, and one of them is to block certain types of content. Most of the campuses have two multilinked T1s, which means right around 3Mb/s. I don't have enough bandwidth to support the world. First, the obvious stuff, like porn, goes into the blocklists. Then I do a little advert filtering. Anonymous web proxies are a no-no, as well as sites dedicated to any sort of large, streaming content. YouTube, Google Video, di.fm, and video portions of ESPN, CNN, and other are blocked, to name a few.
Oh, and Myspace, Friendster, and most of the other social sites are blocked. I challenge you to show me what educational value they have and then show me them being used that way .
And, yes, through a combo of mime-types and regex I block mp3, avi, wmv, mov, and just about every other audio and video type out there. You know what happens when I don't? People spend their time on apple.com waitching movie trailers or something equally unproductive. We got tired of wondering why our VPN or online applications were slow, only to discover people abusing the network. It is not my students right to download the latest game trailer for Whatever's Coming Out Next Month XII (omg!).

With digital content, you can always duplicate onto printed media at will. With your original being a book, you have to do labor-intensive photocopying or scanning and printing to produce a duplicate. I'm not against the idea of paper or books, but especially for research purposes - digital is a vastly more flexible format.

The way I did it was download CGIProxy [jmarshall.com] from my home computer and dropped into the cgi-bin directory of an unfiltered remote webserver that I control. Now whenever some seemingly arbitrary site is blocked (usually under the category of "Personal Sites"), I just go to my own personal (and secret) proxy server and enter the blocked URL. Note: you may have to change all text instances of the word "proxy" within the CGIProxy file to something else for it to work.
MP3 blocking is a little harder to get around, but is possible as WebSense only looks at the extension after the last dot of the filename. The solution is to have your proxy respond to a "fake" URL like "http://somesite.com/somemp3.mp3.prx" and have it pipe the real file located at "http://somesite.com/somemp3.mp3" through the fake URL. I've modified my copy of CGIProxy to do just that, and it works like a champ.
Of course, all this information is for educational purposes only.

Get corkscrew [agroman.net] and use the following in your .ssh/config

Needless to say, I acquired an intimated knowledge of the network protocol layers and how the different mechanisms in each layer works. I would have never acquired such a clear understanding of DNS lookups & tunneling, if I had been given a wide open network. Now, my current office has only a simplified NAT with port 25 outbound blocked (thank you spamware). But I still need to use this when I go to some campus to talk about something & suddenly miss some image or something from my machine (nearly all campuses in India have strict proxies).
