Renesys Reporting Total Internet Blackout in Sudan

Senior Research Engineer, Doug Madory at Renesys reports: "A few hours ago, we observed a total Internet blackout in Sudan and, as we publish this blog, the Internet remains largely unavailable. By count of impacted networks, it is the largest national blackout since Egypt disconnected itself in January 2011. The massive outage came as the government began a violent crackdown on protests triggered by the government’s decision to end fuel subsidies." more

If Demand Is Growing, Why Is Networking World Such a Depressing Place Right Now? Let’s Dig Deeper…

Over at the ECI blog, Jonathan Homa has a nice article about the importance of network planning: In the classic movie, The Graduate (1967), the protagonist is advised on career choices, "In one word – plastics." If you were asked by a young person today, graduating with an engineering or similar degree about a career choice in telecommunications, would you think of responding, "network planning"? Well, probably not... more

CarPIF Regional Connectivity Meeting to Address Affordable and Resilient Internet Access

The Eastern Caribbean island of Grenada has been selected as the venue for the fifth regional meeting of the Caribbean Internet Peering and Interconnection Forum, CarPIF, set for June 12 to 13. The annual international event, which draws Internet giants like Facebook and Google to the region, is focused on developing the Internet in the Caribbean by improving policy and building relationships between network operators and content providers. more

U.S. Now Leading Source of Attack Traffic, Followed by China and Russia

The U.S. became the top attack traffic source in the second quarter of 2010, accounting for 11% of observed attack traffic in total, reports Akamai in its State of the Internet Report released today. According to the report, China and Russia held the second and third place spots, accounting for just over 20% of observed attack traffic. Attack traffic from known mobile networks has been reported to be significantly more concentrated than overall observed attack traffic, with half of the observed mobile attacks coming from just three countries: Italy (25%), Brazil (18%) and Chile (7.5%). more

50 Years of Ethernet

The idea for Ethernet was born fifty years ago in May 1973 when Robert Metcalf coined the word Ethernet. He had been studying ALOHAnet, developed at the University of Hawaii in 1971 and was the first public demonstration of a wireless packet data network. Metcalf used the work Ethernet as a reference to luminiferous aether, a concept postulated in the 17^th century to explain how light could be transmitted through a vacuum. more

Interstate at Rush Hour ...in the Rain ...on a Friday – AKA, Your Enterprise Traffic on the Net

Congestion. Traffic. Two words that draw a visceral response, whether you are commuting to work or managing a network. Managing data traffic used to be easy. Everything was housed in centralized data centers, and all traffic was routed through big, dedicated, effective but expensive "pipes" -- Multiprotocol Label Switching (MPLS) links. When all the applications are at the data center, it makes sense to build private access for all traffic. more

Reframing the Infrastructure Debate

Fast and reliable infrastructure of any kind is good for business. That it's debatable for the Internet shows we still don't understand what the Internet i -- or how, compared to what it costs to build and maintain other forms of infrastructure, it's damned cheap, with economic and social leverage in the extreme. Here's a thought exercise... Imagine no Internet: no data on phones, no ethernet or wi-fi connections at home - or anywhere. No email, no Google, no Facebook, no Amazon, no Skype. That's what we would have if designing the Internet had been left up to phone and cable companies... more

Transparency Meets Sustainability: Announcing the SDIA Open Data Hub

Last month, the Sustainable Digital Infrastructure Alliance (SDIA) announced our Open Data Hub, a resource that's meant to boost transparency, trust, and data availability to help researchers, industry, and society realize a sustainable digital economy. It is essentially our answer to the challenge recognized across the sector: that the lack of reliable data is one of the most foundational issues we face in creating a sustainable ICT ecosystem. more

Amazon’s Huge IoT Network

In a recent blog post, Amazon invited developers to test drive its gigantic IoT network. This network has been labeled 'Sidewalk' and was created by tying together all of Amazon's wireless devices like Amazon Echos and Ring cameras. Amazon claims this huge wireless network now covers 90% of U.S. households. Amazon created the network by transmitting Bluetooth and 900 MHz LoRa signals from its various devices. more

Russian Central Bank Announces Mandatory Cyber-Security Regulations for Domestic Banks

"Russian banks will be faced with a whole range of new regulations, and penalties for non-compliance, when it comes to cyber-security, according to the country's Central Bank," Eugene Gerden reported today in SC Magazine UK more

Happy Birthday, Backbone

Today marks the 20th anniversary of the decommissioning of the NSFNET backbone on April 30 1995, an important milestone in the development of the commercial Internet. The NSFNET was set up by the US National Science Foundation in 1985 to enable university researchers access to five supercomputer sites across the United States, using Internet Protocol technology. In stepping back, the NSF supported a transition to an Internet shaped by market forces, and the explosion of commercial use soon followed. more

Gall’s Law and the Network

In Systemantics: How Systems Really Work and How They Fail, John Gall says: "A complex system that works is invariably found to have evolved from a simple system that worked. A complex system designed from scratch never works and cannot be patched up to make it work. You have to start over with a working simple system." In the software development world, this is called Gall's Law... more

Give Network Administrators a Zero-Impact Firmware Update Solution

Struggles with the firmware update process are well known by Network Administrators in the cable industry. The copious tasks required to complete an end-to-end firmware update are painstaking and error-prone, often making the investment not worth the time it takes to complete the work... imagine doing these manual tasks over and over for hundreds to thousands of devices, many from different vendors, each with its own unique device update path! Clearly, this complex challenge needs a solution. more
