Is Your Planned Submarine Cable Doomed?

Anyone who follows the submarine cable sector knows that a lot of cables have been built in recent years—and investments in new cables keep coming.

I gave a presentation at Submarine Networks World 2019 in Singapore titled "Is Your Planned Submarine Cable Doomed?" My goal was not to identify particular planned cables that I think are doomed to fail, but rather to highlight some of the key flaws we often see when assessing cable operator business plans on behalf of investors.

Signals of Success: What to Look for in Submarine Cable Press Releases

I'm a cynic and you can be one, too!

This was the title of Tim Stronge's presentation during a recent webinar we did with our friends at Ciena.

Our favorite neighborhood cynic came bearing an important public service announcement for webinar attendees: just because you see a flashy slide deck or press release about a new submarine cable doesn't mean it's going to happen.

Our 2019 Provider Connectivity Analysis is Here

TeleGeography's rankings of provider connectivity include analysis based on BGP routing tables, which govern how packets are delivered to their destinations across myriad networks as defined by autonomous system numbers (ASNs).

(Quick reminder: every network must rely on other networks to reach parts of the internet that it does not itself serve; there is no such thing as a ubiquitous internet backbone provider.)

466 Tbps: The Global Internet Continues to Expand

Global internet bandwidth rose last year by only 26%—the lowest annual growth rate seen in at least 15 years—and at a compound annual rate of 28% between 2015 and 2019.

Total international bandwidth now stands at 466 Tbps. The pace of growth is slowing, but it still represents a near-tripling of bandwidth since 2015.

Building and Managing Security Empowered SD-WAN

The benefits of SD-WAN are apparent: more bandwidth, local breakouts, flexibility, etc. That being said, the larger attack surface makes it vital for security to be at the forefront of any modern deployment.

Will New Satellites End the Dominance of Submarine Cables?

There’s been a lot in the press recently about new low-orbit satellites. Rumors abound about content providers wanting to move their internet traffic off of the ocean floor and into space.

Will Bandwidth Prices Eventually be the Same on All Routes?

I call this one the price parity myth—the notion that one day bandwidth prices will be the same on all routes.

Are Content Providers The Biggest Investors in New Submarine Cables?

We’ve written quite a bit about content provider’s investments in new cables. And we’ve seen headlines about Microsoft, Google, Amazon, and Facebook’s big new investments. So does that mean that content providers are the largest investors in new submarine cables?

Data Center Interconnect Goes Undersea: Addressing Voracious Submarine Bandwidth Growth

The majority of new submarine capacity upgrades and cable deployments are designed to address the voracious growth in data flowing between large data centers via submerged information superhighways.

There is simply no networking technology that comes close to optical networks in terms of scalability, reliability, and economies of scale. This means, that as an industry, we must continue to rapidly innovate upon submarine optical networking technology today, and well into the future.

Are New Cables Avoiding Landing in the UK Because of Brexit?

Is it true that new cables are avoiding landing in the UK because of the Brexit vote? I was curious to see if there was any validity to this myth, so I took a closer look.
