Access Providers

Old Cloud vs. New Cloud

Images of clouds have been used when discussing networks for quite some time. When traditional telecoms companies were selling point-to-point circuits a drawing of a cloud was sometimes used. The cloud symbol helped indicate the provider?s domain of responsibility, effectively hid the internal complexity of the network and focused on the end user. This was all fine when the product offered was an end-to-end circuit. more

Quake Damage in Japan

The 8.9-magnitude earthquake in Japan rocked the northeastern portion of the coast. The quake was the strongest to hit Japan in at least a century, sending a tsunami that flooded northern towns and also reached portions of the United States, including Hawaii. The quake was followed by a 7.1-magnitude aftershock. Impact on Internet connectivity... Japan’s Internet performance seemed to have emerged largely unscathed, but concerns continue for the telecommunications infrastructure as the country struggles to meet power demands in a state-of-emergency. more

Japan Earthquake Only Minor Impact on Region’s Internet Infrastructure

James Cowie from Renesys reports: "8.9 magnitude earthquake in Japan has had surprisingly limited impacts on the structure and routing dynamics of the regional Internet. Of roughly 6,000 Japanese network prefixes in the global routing table, only about 100 were temporarily withdrawn from service -- and that number has actually decreased in the hours since the event. Other carriers around the region have reported congestion and drops in traffic due to follow-on effects of the quake, but most websites are up and operational, and the Internet is available to support critical communications." more

Ottawa Committed to Overturn CRTC Decision on Usage-Based Internet Billing

Canadian Industry Minister Tony Clement has announced that the Harper government will overturn the CRTC's decision that effectively ends "unlimited use" Internet plans if the regulator doesn't rescind the decision itself. more

Libya Using a Different Internet Strategy than Egypt

In a Renesys blog post, James Cowie writes: "Why did Libya put its Internet in 'warm standby mode' instead of just taking it down, as Egypt did? Perhaps because they're learning from Mubarak's experience. Cutting off the Internet at the routing level (powering down the Internet exchange point, going after the remaining providers with secret police to enact a low-level shutdown) was a technically unsophisticated desperation move on Egypt's part." more

Comcast’s Impressive System for Notifying Infected Users

Pretty much as long as there've been computers, one of the biggest challenges has been user education. How do you create software smart enough to inform a user when they're about to do something potentially disastrous - or, worse, when something disastrous has been done to them? As one of the world's largest access providers, Comcast has put a ton of thought into developing a notification system for their users. The solution Comcast developed involves, in effect, hijacking HTTP requests... more

Registries, Registrars, Resellers and the Fight Against Cyber Crime: The EU-US Meeting

On 24 and 25 February 2011 the European Commission, DG Home Affairs, organised a meeting on cyber crime in cooperation with the US government, Department of Justice, with representatives of the law enforcement community, registries and registrars. The basis of the discussion was the RAA due diligence recommendations (hence: the recommendations) as presented by LEAs in the past years during ICANN meetings. The meeting was constructive, surprising and fruitful. I give some background, but what I would like to stress here is what, in my opinion, could be a way forward after the meeting. more

Collecting Cybercrime Data: Can Signal Spam Be a Piece of the Puzzle?

The gathering of coherent data on cybercrime is a problem most countries haven't found a solution for. So far. In 2011 it is a well known fact that spam, cybercrime and botnets are all interrelated. The French database Signal Spam may be a significant part of the solution to gather, analyse and distribute data on spam, phishing, cybercrimes and botnets, but also be a forum in which commercial mass e-mail senders and ISPs can work on trust. more

Internet Service Restored in Egypt

Renesys reports that Internet services in Egypt have been restored. According to the report, Egyptian Internet providers returned to the Internet at 09:29:31 UTC (11:29am Cairo time). "Websites such as the Egyptian Stock Exchange, Commercial International Bank of Egypt, MCDR, and the US Embassy in Cairo, are once again reachable. All major Egyptian ISPs appear to have readvertised routes to their domestic customer networks in the global routing table."

Where High Speed Internet Meets Smart Grid

Advanced internet technologies, energy management and the smart grid are coming together in a mid-sized city in South Tennessee. Tennessee based utility EPB has completed one of the fastest internet pipelines in the world and has activated the first automated switches on its electricity network. The combination constitutes the backbone for a DOE-funded smart grid network that is expected to save the utility and businesses tens of millions of dollars annually. more

Uncertain Knowledge

The establishment media frequently attack the Internet as spreading inaccurate, unchecked rumors as news. While that is certainly true, the Internet is also demonstrating that the establishment media is no better. In the past weeks we have been told that the Stuxnet virus was written by US and Israeli intelligence. The evidence? Some un-named Israeli intelligence officers grinned broadly at reporters when the subject was mentioned. Is that what it has come to? more

Some Observations on Reachability of Egyptian Networks and Providers

Different media are reporting that Internet and other forms of electronic communications are being disrupted in Egypt. Presumably after a government order in response to the protests. Looking at BGP data we can confirm that according to our analysis 88% of the ‘Egyptian Internet’ has fallen of the Internet. In this post I’ll share some observations I made with regards to the reachability of Egyptian networks and providers. more

Egyptian Government Shuts Down Most Internet and Cell Services

The Egyptian government has disabled most Internet and cell phone services in an apparent effort to disrupt the anti-government protests gripping the country. Egypt's four primary Internet providers all stopped moving data early Friday, effectively cutting off Egyptians from the outside world and each other. more

Egypt’s Internet Blocked - I Call on My Friend Tarek Kamel to Unblock It and Join His People

Internet all over Egypt has been blocked in an unprecedented revolt. I call on my friend Tarek Kamel, Egypt's Minister of Telecommunication, to overturn this oppressive decision and to unblock the Internet in all Egypt immediately and to join his people in their peaceful revolt. I have known Tarek Kamel for more than a decade and long before he became minister back in the days when he used to say he had no authority and that the decisions were in the hands of his boss and that he was a mere decision-less adviser to then Minister of Telecommunication, Mr. Nazif. more

21st Century Triple Networks: Ubiquitous 4G, WiFi, & Wires

The best engineers on the planet are coming to the same conclusion: a hybrid 4G/WiFi/landline network is the way to meet mobile demand. Folks like John Donovan of AT&T and Masayoshi Son of Softbank in Japan had this vision around 2007-2008. As the iPhone/iPad/Android made the coming demand clear, networks planners around the world evolved similar strategies. more
