There have been lots of press stories in the last day reporting on what the Internet shutdown in Myanmar looked like for people there, and that's the important story. This is what it looked like to the rest of the world, from an Internet infrastructure standpoint. The connection between Myanmar and the rest of the world appears to be turned back on, at least temporarily. The 45 megabit per second circuit connecting Myanmar to Kuala Lumpur that is Myanmar's primary connection to the Internet came back up at 14:27 UTC today. It had mostly been "hard down," indicating either that it had been unplugged or that the router it was connected to was turned off, with the exception of a few brief periods since September 28. Myanmar's country code top level domain, .MM, disappeared... more
A deal announced today between British Telecom and upstart FON allows BT's Internet customers to share their own broadband connections via WiFi and, in turn, be able to access WiFi free at "thousands" (doesn't say how many) of FON hotspots around the world operated by other Foneros... When you buy home Internet access from BT and opt into this plan, you are also buying roaming access at no extra charge. The technology is supposed to assure that the part of the connection which you share is segregated from your own access so that there are no security problems caused by the sharing. more
Vonage's latest woes are written up by Om Malik in Vonage: How Low Can You Go. More interesting than Om's reportage (Sprint wins case, Vonage ordered to pay damages, stock drops to $1.30) is the commentary afterward, in which one reader takes Om to task for the "gleeful" way in which he reports the demise of the VoIP companies... Boosters made the argument that VoIP was fundamentally cheaper than the TDM systems that phone companies deploy, and so therefore they enjoyed a price advantage in the market place. Anyone in the business of supplying telecom equipment, however, will tell you that the argument is flawed... more
On August 23 ( while I was in China) a list member Lee S. Drybrugh wrote in jest: I happened to bump into Peter Cochrane stating, "The good news is -- bandwidth is free -- and we have an infinite supply." Next by sheer accident I bumped into this in relation to Gilder, "Telecosm argues that the world is beginning to realise that bandwidth is not a scarce resource (as was once thought) but is in factinfinite." Can anyone explain this infinite bandwidth as I think I am getting ripped off by my ISP if this is true? Craig Partridge then offered what I think is a very good commentary of a difficult question where the answer depends very much on context... more
DNS rebinding attacks are real and can be carried out in the real world. They can penetrate through browsers, Java, Flash, Adobe and can have serious implications for Web 2.0-type applications that pack more code and action onto the client. Such an attack can convert browsers into open network proxies and get around firewalls to access internal documents and services. It requires less than $100 to temporarily hijack 100,000 IP addresses for sending spam and defrauding pay-per-click advertisers. Everyone is at risk and relying on network firewalls is simply not enough. In a paper released by Stanford Security Lab, "Protecting Browsers from DNS Rebinding Attacks," authors Collin Jackson, Adam Barth, Andrew Bortz, Weidong Shao, and Dan Boneh provide ample detail about the nature of this attack as well as strong defenses that can be put in place in order to help protect modern browsers. more
Last month's column looked at the exhaustion of the IPv4 unallocated address pool and the state of preparedness in the Internet to grapple with this issue... There has been a considerable volume of discussion in various IPv6 and address policy forums across the world about how we should respond to this situation in terms of development of address distribution policies. Is it possible to devise address management policies that might both lessen some of the more harmful potential impacts of this forthcoming hiatus in IPv4 address supply, and also provide some impetus to industry to move in the originally intended direction to transition into an IPv6 network? more
My friend Kurtis writes in his blog some points he has been thinking of while discussing "when we run out of IPv4 addresses". In reality, as he points out so well, we will not run out. It will be harder to get addresses. It is also the case that unfortunately people that push for IPv6 claim IPv6 will solve all different kinds of problem. Possibly also the starvation problems in the world... more
Funny how some topics seem sit on a quiet back burner for years, and then all of a sudden become matters of relatively intense attention. Over the past few weeks we've seen a number of pronouncements on the imminent exhaustion of the IP version 4 address pools. Not only have some of the Regional Internet Registries (RIRs) and some national registry bodies made public statements on the topic, we've now seen ICANN also make its pronouncement on this topic... Why the sudden uptake of interest in this topic? I suspect that a small part of this may be my fault! more
The term "last mile" highlights the fact that we are the consumers at the end of a broadband "pipe". Saying "first mile" is a little better but the Internet is not a pipe to or from somewhere else. It's about what we can do locally and then what we can do when we interconnect with other neighborhoods. It's better to describe our neighborhood as the first square mile. Telecom is about selling us services; the Internet is about what we can do ourselves locally and then interconnecting with others everywhere. In writing the First Square Mile - Our Neighborhood essay which I just posted I came to better understand the fundamental difference between the world of telecom which is about giving you choices and the Internet which provides opportunity to discover what we can't anticipate... more
A friend who read my Creating Sustainable Network Neutrality paper wrote to say, "Help me understand what is so bad about treating different types of communications differently." That's a really good question! If you want to offer vertically integrated services on special purpose networks, such as video entertainment or pager service or telephony, I do not have a problem with that, provided you don't use your market power to impede Internet applications that offer competing services... more
