A Look at How the Internet Routes Around Damage: Measuring Global Effects of Storm Sandy

Hurricane Sandy caused major damage in both the Caribbean and the North-Eastern part of the USA. In an earlier article (RIPE Atlas - Superstorm Sandy) we showed data on 15 RIPE Atlas probes that are located in or near the affected areas in the USA. Most of these locations now appear to be back to normal round trip times to targets we monitor. But the effects of Hurricane Sandy were felt beyond the immediately affected area. more

The Recent DDoS Attacks on Banks: 7 Key Lessons

Starting in mid-September, one of the largest and most sophisticated DDoS attacks ever targeted the titans of American banking. Initially, victims included Bank of America, JPMorgan Chase, Wells Fargo, PNC Bank, and U.S. Bancorp. In the weeks to come, others would also feel the pain. Websites crashed, customers were unable to make transactions and IT professionals and PR gurus went into panic mode. Leon Panetta, U.S. Secretary of Defense, said the attacks foreshadowed a "Cyber Pearl Harbor." more

Telcos Cannot Wind Back the Clock

The proposals by the European and Arab telcos that are being considered at the World Conference on International Telecommunications (WCIT) conference in Dubai later this year are most certainly facing defeat. This is not because the USA believes that the international telecommunications regulations (ITR) cannot be discussed by the ITU. America has a rather strange set of national regulations in which they have combined internet infrastructure and content -- and as such they claim that this no longer has anything to do with telecommunications. more

Lessons from Sandy: Building Networks and Cyber-Infrastructure to Survive Climate Change

Hurricane Sandy has been a badly needed wake up call for the Internet community as to the threat of climate change. Although most people have forgotten, Sandy is the second hurricane to hit New York in as many years with Irene last August and a third tropical depression headed to New York at the time of this writing. Two, supposedly once in a hundred year storms, within such a short time frame should even make the most die-hard denialist that something's afoot. more

Names, Numbers and Beyond…

Couple of weeks ago I started a new initiative called "Names, Numbers and Beyond". I started this as I genuinely think we are facing big issues due to the uncontrolled and non-standard growth of the IP and Name space used today and tomorrow. To keep in control and make everything manageable, parcelling out IP address space and the use of tight naming standards/policies is necessary to make networks work better and make them achievable. more

Cyberattackers Targeting Iranian Infrastructure and Communications Companies

Internet based attacks have targeted Iranian infrastructure and communications companies, disrupting Internet access across the country, according to today's reports. Country's secretary of the High Council of Cyberspace, has been quoted telling the Iranian Labour News Agency: "Yesterday we had a heavy attack against the country's infrastructure and communications companies which has forced us to limit the Internet. ... Presently we have constant cyber attacks in the country." more

A Short History of ITU Network Security Activity

Since the inception of ITU precursors in 1850, its various bodies have treated the subject of telecommunication network security as both an obligation of signatories to the treaty instruments as well as an ongoing collaborative activity. However, what it actually did in those activities was constrained by its jurisdiction and participant competency -- which encompassed international public telecommunication services provided primarily by designated government agency service providers known as PTTs. more

Rebalancing Telco Infrastructure Investments

One of the reasons telecommunications has been so successful for more than 160 years is that it adopted a strategy that resulted in a seamless network all around the world. You can pick up a phone anywhere in the world and, with little or no instruction, make a call to anybody else in the world without worrying what phones and technology they are using on the other end of the line... But during that process the nature of the network operators changed. more

National Broadband, Leadership or Procrastination

There is no doubt that any national infrastructure plan of the magnitude of national broadband networks as they are currently rolled out in 9 countries and which policies have been put in place in another 110 countries will have questions attached to it. Furthermore, this infrastructure is being developed for the digital economy, which, in itself, is a fast-moving world. Five years ago there were no smartphones, tablets, mobile apps or smart TVs. more

Mobile Infrastructure Running Out of Steam

The enormous growth in mobile usage, doubling each year, is set to continue for several years in a row. According to Ericsson, by 2020 mobile operators will need to provide one thousand times the capacity that was required in 2010. Our assessment at BuddeComm is that the mobile industry has already fallen behind in delivering the capacity needed today, let alone coping with the enormous growth ahead; and that this situation will deteriorate before it improves. more

The Role of Mobile Broadband in the Overall Telecoms Market

The fixed broadband network is the infrastructure needed to meet the needs, both economic and societal, of developed markets. While some people in some developed markets have abandoned their fixed telephone connection in favour of all-mobile solutions, the majority (90% plus) still have both a fixed and a mobile connection... And so wireless broadband and FttH will develop, in a complementary and harmonious way. There are several reasons for this. more

Tracking Outages

The idea of tracking data outages spawned from an early discussion on the outages forum including feedback from an outages survey about having a status page for (un)planned outages as a central resource. The purpose of such effort is to have a wider focus that one could view as opposed to having to check dozens of provider status pages. There were many ideas put forth but nothing really panned out and things kinda fell on the back burner. more

IPv6: The Summer It Finally Happened

A decade old guessing game finally came to an end during these 2012 summer months. America was supposed to be hopelessly behind while Europe had not much to show after a decade of spending lavishly EU money on IPv6 related projects. China and Japan were thought to be light years ahead of everybody else. But in the end, it was the might of the American Content Industry that tipped the scales. more

OpenFlow - The Programmable Network Revolution

Over the past few months I have made regular references to OpenFlow. This is an exciting new development that fits in very well with several of the next generation technology developments that we have discussed in some detail over the past few years -- new developments such smart cities and smart societies, the internet of things. Such networks need to operate more on a horizontal level, rather than the usual vertical connection between a computing device and the users. more

How to Evaluate Performance of a DNS Resolver

Ten years ago everyone evaluating DNS solutions was always concerned about performance. Broadband networks were getting faster, providers were serving more users, and web pages and applications increasingly stressed the DNS. Viruses were a factor too as they could rapidly become the straw that broke the camel's back of a large ISP's DNS servers. The last thing a provider needed was a bottleneck, so DNS resolution speed became more and more visible, and performance was everything. more
