How Brazil’s Massive Power Outage Affected Telecommunications and Internet Routing System

Last night millions of people were left without electricity in two of Brazils' biggest cities, São Paulo and Rio de Janeiro, as a result of a massive power failure. Consequently the outage has also had a significant impact on telecommunications and the Internet routing system in a number of South American regions. According to a related report released today by Renesys, while Brazil took the largest hit, Paraguayan and Uruguayan networks also went out "as a result of the largest regional power outage to hit Brazil and its neighbors in several years." more

Yemen’s Submarine Cable Repairs Hindered by Political Dispute

Repair efforts for three crucial submarine internet cables damaged in the Red Sea are being obstructed by political disputes over access to Yemeni waters. more

DNSSEC Deployment Among ISPs: The Why, How, and What

It's no secret that Comcast has been leading the charge of DNSSEC deployment among ISPs. For the past couple years, Comcast has been testing and pushing for the widespread adoption of DNSSEC. In the spirit of increasing adoption, I thought I would interview the DNS gurus at Comcast to see what they've learned and what advice they would give other ISPs considering DNSSEC deployment. more

Malaysia Reverses Decision on Controversial DNS Redirection Policy

The Malaysian government has backtracked on its recent decision to require Internet Service Providers (ISPs) to redirect Domain Name System (DNS) traffic away from third-party servers like Google Public DNS and Cloudflare. more

Lessons from the O2 Network Outage: The Real Cost of Manual Processes

More than 30 million people lost their data connectivity on December 6, 2018, in the United Kingdom as O2's network suffered from a nationwide service outage. Based on several reports, the incident was caused by a human error at Ericsson, the telecoms supplier responsible for operating certain parts of the O2 network. To compensate for the downtime and tarnished reputation, the O2 management is now reportedly seeking damages of up to a hundred million pounds from Ericsson. more

Old New Telco Thinking

Ahh, so the telecom incumbents have come up with a "new" idea for the Internet -- usage-based pricing. That's right, more usage (for things like VOIP and video especially) means more costs to operate the network, so users should pay by the bit, or some similar metric. It's all so logical! But wait a minute. I thought what sparked the consumer Internet revolution was the fact that ISPs didn't charge by the minute, but offered flat-rate monthly fees. And what catalyzed the boom in cellular usage here in the US was the shift from heavily usage-based pricing to the largely flat rates we see today... more

90% of Sky UK Broadband Customers Now IPv6 Enabled, Says Network is “Future Proofed”

"Sky completes roll out of IPv6 becoming the first major UK Internet provider to future-proof its service for customers," announced the company in a press release on Tuesday. more

The Search for Net Neutrality

My weekly Law Bytes column (Toronto Star version, freely available version) examines the growing trend toward a two-tiered Internet, which upends the longstanding principle of network neutrality under which ISPs treat all data equally. I argue that the network neutrality principle has served ISPs, Internet companies, and Internet users well. It has enabled ISPs to plausibly argue that they function much like common carriers and that they should therefore be exempt from liability for the content that passes through their systems. ...Notwithstanding its benefits, in recent months ISPs have begun to chip away at the principle. more

LTE and Spectrum Stupidity

Mobile operators are counting on Long Term Evolution (LTE) technology to handle surging demand for mobile data access. But LTE developers made some poor choices, cutting spectral efficiency and thus driving up operator costs. LTE was envisioned as an all IP system, but the RF allocations follow the voice-centric approach of earlier generations. While LTE standards allow for either Frequency Division Duplexing (FDD) or Time Division Duplexing (TDD), all initial LTE equipment uses FDD. FDD requires two separate blocks of spectrum... more

China on Its Way to Becoming a Formidable Satellite Internet Service Competitor

In a study of the Internet in China in the late 1990s, my colleagues and I observed that "China has been able to execute plans effectively by allocating resources to competing, government-owned enterprises," and Kai-Fu Lee shows that they have pursued a similar strategy with respect to AI. Now they are doing the same with low-Earth orbit (LEO) broadband satellite constellations. more

The Demand and Supply Imbalance in Telecoms

You can't open a newspaper today, listen to the radio, or watch TV without hearing about the enormous explosion in the use of telecommunications technology - be it fixed or mobile broadband, the internet, social media, smartphones, tablets, wearables, IoT, cloud computing, the list is endless... Yet, at the same time, many telcos and ISPs are struggling to maintain their profitability. This defies economic logic. more

Knowing Less

The announcement yesterday morning in the Times that New York State AG Andrew Cuomo had reached an agreement with three US network operators (Verizon, Sprint, and Time Warner) about blocking child pornography was both less and more important than it appeared. It's less important in that part of the agreement covers something ISPs already do... more

China Temporarily Cuts Itself Off from the Global Internet

China briefly disconnected from much of the global internet for over an hour on Wednesday, following a disruption traced to the country's "Great Firewall." According to activist group Great Firewall Report, the outage began at 12:34 a.m. Beijing time and lasted until 1:48 a.m. on August 20. more

Another Portent of the Decline and Fall of the Telco

The Swedish carrier group Telia has recently announced the sale of its international wholesale business to Polhelm Infra, an infrastructure investment manager jointly owned by a number of Swedish pension funds. Why would a telco operator sell off what was a core part of its operation to a pension fund? The Internet was originally conceived as a telephone network for computers. (I should mention that this was not a concept that was unique to the Internet at the time. more

FCC and Comcast: Reasonably Vague

So, the FCC will recommend that Comcast be "punished" or receive "sanctions" for its peer-to-peer throttling practice. And the network neutrality debate goes on, as does its ambiguities and vagueness. Even if you hate Comcast and agree with the net neutrality argument and the FCC's decision, one thing Comcast is correct in saying is that "reasonable network management" specified by the FCC in network neutrality policy set in 2005 is vague. Actually, the term "network management" by itself is broad before you even try to interpret what is meant by "reasonable", and it is not exactly correct in its application here... more
