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

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

Spanish Joint-Network Investment in FttH Seeing Returns

Spain's economic anguish has had a number of repercussions for the country's telcos, with stable or declining revenue causing much nervousness as operators struggle to fund essential investment in spectrum and both fixed-line and mobile networks. Earlier this year Vodafone felt the pinch, announcing plans to cut its Spanish workforce by up to 1,000. Though general economic conditions have not helped, the move partly resulted from its own decisions. The company saw revenue drop for several quarters and so decided to save money by cutting handset subsidies. more

Complete Internet Shutdown Reported in Syria

While Syria's Internet disruptions in the recent past have been linked to Government's efforts to prevent cheating during national high school exams, today's complete Internet shutdown reported by Dyn Research is unknown and does not appear to be exam-related. more

Google Not the Only Company Testing Wireless Access by High-Altitude Balloons

Oceus Networks Inc., a mobile 4G LTE broadband networking provider, recently demonstrated the efficacy of a deployable 4G LTE solution on a high-altitude balloon platform, which can be used to rapidly provide broadband coverage and communications services to first responders within the first 72 hours following an emergency or natural disaster. more

NANOG’s Edward McNair Delivers Keynote Address at CaribNOG 17

Edward Mc Nair, executive director of the North American Network Operators Group (NANOG), delivered the keynote at the seventeenth regional meeting of the Caribbean Network Operators Group (CaribNOG), held from April 10 to 12 at the Hilton in Bridgetown, Barbados. McNair's keynote focused on the important role that network operator groups, or NOGs, play in building an Internet that serves the specific needs of the people in the region. 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

Just One Bit

I'm never surprised by the ability of an IETF Working Group to obsess over what to any outside observer would appear to be a completely trivial matter. Even so, I was impressed to see a large-scale discussion emerge over a single bit in a transport protocol being standardized by the IETF. Is this an example of a severe overload of obsessive-compulsive behaviour? Or does this single bit represent a major point of design principle... more

Centralizing DNS Data for Security, Compliance, and Performance

Private DNS data lakes consolidate fragmented logs into a centralised platform, improving visibility, security, and compliance. They enable advanced analytics, strengthen threat detection, and help organisations optimise network performance in increasingly complex IT environments. more

Tips for Managing Your Company’s Shadow IT Issues

Shadow IT -- the use of unsanctioned software and services by employees -- is a problem. It's a big one. According to Forbes, 72 percent of executives don't know how many "shadow" apps are being used on their network. Beyond overloading network resources and impacting data compliance, there is also the real threat of security breaches from unapproved apps. Managing IT you can't see is no easy task, but fortunately it's not impossible. Here are five tips to help bring light to the shadows. more

Making Internet Faster: Google, OpenDNS and Others Announce Joint Effort

Google, OpenDNS, content delivery networks and other operators have announced a joint effort called "The Global Internet Speedup," to "make the Internet faster". According to the group, this collaboration will be executed via an open IETF proposed standard called "edns-client-subnet" in order to help better direct content to users thereby decreasing latency, decreasing congestion, increasing transfer speeds and helping the Internet to scale faster and further. more

An Internet Infrastructure Perspective on AI Service Provision

This study analyzes the differences in domain name and IP address strategies among a number of current mainstream artificial intelligence (AI) service providers. We find that these technical choices not only reflect deployment decisions but also deep-seated corporate knowledge and capabilities in Internet infrastructure service provision, as well as brand positioning and market strategies. more

CIDR in Networking: Improved IP Routing Efficiency

CIDR (Classless Inter-Domain Routing) is a routing system in which network engineers can distribute IP addresses based on the size of their specific network. This is more efficient than the previous system, which assigned IP addresses depending on whether the size of a network fits into one of only three sizes: Class A, Class B, and Class C. more

Are Telcos Becoming Slum Landlords?

In the 1950s and 60s, large numbers of immigrants came to London from the Caribbean and other Commonwealth countries. They had few resources, yet needed somewhere to live. Many fell prey to exploitative landlords. These unscrupulous rentiers packed tenants into formerly swanky parts of town, which then became slums. This process even birthed a new word in British English - "Rachmanism" - to define the archetypal unethical treatment as practised by one notorious landlord. more

Why Integrating IPAM Matters and How to Achieve It

IPAM solutions are the source of truth for IP resources on the network, but when performing IPAM functions such as assignments, reconciliations, DNS updates, network plans, or Regional Internet Registry (RIR) requests, IPAM is often limited by its integration with an OSS. Operational teams can find it challenging to complete routine tasks without an integrated IPAM solution due to siloed data pools and swivel-chair environments. more
