Sounds great but isn't accurate sorry...I do this all the time and 6ms for such a simple path would have financial customers showing me the door:-)
I just deployed a network somewhere in Europe where crossing three levels of switches (each at 700ns of delay) with 10Gbps interconnects gave us acceptable (and yes that was the word the customer used) performance:-)
I agree that your 1993 stats are painful but pain is relative...:-)
300ms truly is the serialization delay from an old analogue modem and I stand by the rest of what I said. The original poster should not accept this level of service in 2012 unless he's so far away from the nearest pop that the delay is justifiable which would surprise me in the continental US.
Right now I'm getting 220ms rtt to www.tires.com which appears to be hosted in Phoenix, AZ.
That being said...I'm in Normandy, France right now, using my laptop across wifi then ADSL before hitting a decent provider backbone, and I am transferring a large FTP file at max bandwidth at the same time.
If I had 300ms from my provider I would do anything I could to get off their network.
3ms wouldn't shock me as it might be 10Mbps across anything. Might be wifi, wireless, VPLS, DSLAM, might be transparently firewalled. Might be 10Mbps Ethernet but shared with some slight congestion. Wouldn't be worth complaining about 3ms unless you're doing realtime financial transactions or pvp.
When a major US carrier (who shall remain unnamed) first deployed their nationwide MPLS service they, for cost reasons, had only one MPLS device in Texas and L2 backhauled every circuit sold in Texas to that one device. Transparent to the customer but you can see that first hop would have some variance depending on how far the customer site was from that one MPLS device.
300ms is the serialization delay on a 56kbps modem. Doing any modern email with any sizable attachment would be painful at best and would more likely experience timeouts. Browsing the web with 300ms of delay would be painful.
Keeping in mind that this delay is apparently inside his ISP network I think that there is no reason that he should accept 300ms unless his ISP is an inter-island carrier and the test servers are on another island or something.
Generally speaking, on a 10Mbps broadband connection I would expect 1-3 milliseconds to the first hop and a few milliseconds per hop additional inside the regional network.
If you start hopping to other continents or if you're located on an island and have to have a satellite uplink or long haul inter-island or intercontinental fiber then you need to adjust your expectations upwards from there. Figure on a half second delay for a satellite link (accounts for both up and down) - 300 isn't enough for satellite so I think you're not having this problem.
What's your traceroute to various places look like (to their test servers for example, and to other locations around the Internet)? Is your delay right from the first hop or does it come later in the ISP network? (I'll assume the delay is on your own ISP network as the delay is to their own test servers).
My point was that such things will be fought over between the left and the right, between the educated and the ignorant, between the moderates and the extremists. The actual details of any specific case are irrelevant but I chose the Texas textbook case as something recent and highly contentious.
With regard to your post, you should provide references to back up your statements as they appear to directly conflict the references I posted.
From the Washington Post article I referenced: "The curriculum plays down the role of Thomas Jefferson among the founding fathers, questions the separation of church and state, and claims that the U.S. government was infiltrated by Communists during the Cold War."
Math perhaps but anything with any political aspect will be fought over, i.e. Texas re-writing history textbooks in an effort to lesson the constitutional barriers of separation of church and state.
At a glance, I don't see any hashes to validate the source files that are being downloaded.
If I were the Feds (of any country) or anyone who wants to inject malware (ie the recent Anonymous trojan), I'd replace the installers or redirect when people go to get source files or updates.
If I understood TFA correctly, the trojan was not distributed by Anonymous but by others who basically hijacked the distro, redirecting the wannabee DDOSers to another executable which contained the trojan.

The harder you've worked for it, the greater the symbolism of rejecting it becomes.
You could choose to start or join an organization with the same values, minus the discrimination.
Scenario C) Financial markets crash Bank and other financial account information is scrambled The systems in most fortune 500 firms crash Communications satellites suddenly don't work anymore Landline and mobile phone systems stop working
Scenario D) All the above plus any military systems that haven't been well enough protected
Keep in mind as well, that a cyber attack can be a precursor to a physical attack (ie taking down air defense and then sending in your very real jets / missiles)
I can easily imagine 'losing the Internet' if the shit hits the fan (and by the way, I work on Internet, telco and financial sector IP infrastructure constantly so I'm not completely ignorant of what I'm talking about).
Consider how much networking (and everything else) equipment is made in China, for example.
Is anyone looking for kill code in this hardware? No idea but I think that anyone who buys from a country that is as continually abrasive and invasive as China should assume that they're getting what they're paying for...and maybe a bit more besides.
With regard to pulling the plug, you would have to know ahead of time that the attack was going to happen which seems improbable. If you pull the plug after the attack you might find a lot of your infrastructure down at all levels from traffic control through financial market trading infrastructure.
Anything important should be airgapped. Anything critical should be airgapped and should have low level code analysis on source and updates.
That being said I doubt that our processes and procedures are enough to defend against something like stuxnet, especially if it's buried in the hardware.
"...an effect that psychologists call Delayed Auditory Feedback (DAF), which has long been known to interrupt your speech (you might’ve experienced the same effect if you’ve ever heard your own voice echoing through Skype or another voice comms program). According to the researchers, DAF doesn’t cause physical discomfort, but the fact that you’re unable to talk is obviously quite stressful."
I thought it did something neat like send out sound cancelling vibrations that actually stopped the sound from traveling through air but this gadget actually relies on a psychological reaction to hearing your own voice (http://en.wikipedia.org/wiki/Delayed_Auditory_Feedback). Might work on nice polite Japanese people, not sure it would work on people who just don't care or who care enough about what they're saying to tolerate the 'stress' of the audio feedback. It also doesn't seem very difficult to get around to me...a decent set of earplugs should do it.
Failing that, if this does actually work I'm sure someone could come up with a voice jamming jammer:-)/facepalm
Sounds brilliant, it really does, but at the end of the day, if it becomes too difficult for the government (whichever) to control, it will be made illegal.
Forgive my ignorance in thinking that the US invented the Internet (http://en.wikipedia.org/wiki/Internet) but perhaps you can explain to me the bits about the Brit who actually invented it and the European funding behind it?

I didn't say the addition was wrong genius, just that the overall statement is wrong.
The current crop of datacenter switches use cut through. Have a look at Juniper QFX and Cisco Nexus switches.

Serialization delay is the time that it takes to write to the media. The faster the media, the slower the serialization delay.

Another example, staying in Texas, is teaching creationism (aka intelligent design) vs teaching evolution (aka what all of science tells us to be the actual way things happened):
