You're Building a Submarine Cable Where?

It turns out that the Arctic isn't the easiest place to lay a cable.

Expensive and logistically challenging, Arctic cables are at the center of one of our recommended reads for this month. If you're up for a story that includes forged signatures, Arctic ambitions, and the dynamite quote, “The question is not why Elizabeth did it, but rather, how did she think she’d get away with it?”—then keep reading, my friends.

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.

5G Rollouts Put the Pedal to the Metal

Lots of 5G news this week. Most notably, almost a quarter-billion new LTE connections were added worldwide in Q2 2019, according to 5G Americas.

You can read all about 5G mania below. There are also some worthy headlines about internet speeds, India's telecom battle, and a great interview between Recode's Kara Swisher and Huawei’s chief security officer in the U.S. Andy Purdy. 

Behind the Headlines: Recent Submarine Network News, Explained

This year has been—and will continue to be—a busy one in the submarine networking industry. Several new submarine cables have already been announced, deployed, or put into service.

How Do You Become Africa's Largest Telco?

For better or worse, MTN has been unafraid of doing business in locations experiencing war, political turmoil, and disaster.

This strategy has made them one of the biggest telcos in Africa—but it hasn't come without cost. The Wall Street Journal's recent profile earns the top spot on our list of monthly reads.

Wargaming an MPLS Core Hybrid: How to do SD-WAN Without Losing MPLS

Howdy folks, Greg is out on vacation (adventuring in the magical kingdom of Orlando, Florida) so I will be filling in for a bit to continue our series on “wargaming” WAN scenarios.

Adding SD-WAN, Keeping MPLS

My wife has a brutal Northern Virginia commute; she drives about 80 miles a day. Recently, we decided it was time for a new car for her.

Wargaming Your WAN: MPLS-Broadband Edition

Hello and welcome to the third entry in our series about wargaming WAN configuration scenarios. We’ve made it to the MPLS-broadband edition!

Before we continue: if you haven’t read the previous entries where I introduce our hypothetical WAN and then add local internet breakouts with DIA, it probably makes sense to do that before you dive into this one. (This scenario mirrors our last, but replaces DIA with ISP-sourced business broadband.)
