Taiwan Earthquake Just a Year Ago

And speaking of cable cuts that massively disrupt global communications, it was just over a year ago, in December 2006, when an earthquake took out a number of Pacific cables.

Those cable cuts took out much voice and Internet communications in many parts of Asia, as well as 60 percent of capacity between Asia and the United States.

The 2006 Hengchun earthquake occurred on December 26, 2006 at 12:25 UTC (20:25 local time), with an epicenter off the southwest coast of Taiwan, approximately 22.8 km west southwest of Hengchun, Pingtung County, Taiwan, with an exact hypocenter 21.9 km deep in the Luzon Strait ( [show location on an interactive map] 21.89° N 120.56° E), which connects the South China Sea with the Philippine Sea.

Cable Cuts Not That Rare

In the winter of 2000, Telstra, Australia's biggest Internet service provider had a cable cut of its own on Nov. 19, when its Internet backbone cable, sitting in less than 100 feet of seawater about 40 miles off Singapore, was damaged by unknown causes.

Telstra at that time relied on the cable, known as SEA-ME-WE 3 (for Southeast Asia, Middle East and Western Europe) for more than 60 percent of its Internet transmission capacity.

About 23,600 miles long, the cable connected 33 countries, touching places as diverse as Singapore, Malaysia, Thailand, India, Saudi Arabia, Egypt, Djibouti, Turkey, Greece, Italy, Portugal, France and the U.K.

WiMAX: Ultimate Role Unclear

Clearwire touts its vision of the future as mobile Internet. But so far, its customer base is a replacement for dial-up, cable modem or Digital Subscriber Line service. Just four percent of its customers appear to substituting a mobile service for WiMAX.

That isn't to say the customer base and apparent value proposition will remain as it currently is. WiMAX someday may compete more directly for the broadband-equipped mobile customer base.

That isn't the case today, where Clearwire seems to be competing with cable and telco fixed broadband services. At some point, the mobility play is supposed to have Clearwire and WiMAX competing more robustly for the data card and smart mobile phone customer. But lots of challenges remain.

WiMAX might someday primarily be a platform for mobile broadband. In Sprint's case, it might primarily be the next-generation replacement for 3G broadband. If the former winds up being the case, cost control will be more important. If the latter, feature richness will be more important.

The reason cost control is more important for a mobile broadband network is that the revenue sources will be less robust, on a "dollar for bit" basis, compared to networks that make lots of revenue from voice and texting services, which are highly efficient, on a "revenue for bit" basis.

Advertising also is more important if mobile broadband winds up being the primary attraction for WiMAX users. That suggests content access is more important than communications, and that in turn means media, and media always means advertising.

Cable Cut Disrupts India Call Centers

Cable cuts that damaged two undersea Internet cables off Egypt's coast now are disrupting call centers in India, the Wall Street Journal reports. Reportedly, about half of India's Internet bandwidth now is disrupted, and voice traffic to the United States and Europe also are affected.

It could take a week or two to fix the cables, in part because of bad weather, some executives say.

Users in India, Egypt, Qatar, Saudi Arabia, the United Arab Emirates, Kuwait and Bahrain are affected by the outages.

Observers think an anchor might have snagged the cables. At least that's what Flag Telecom Group Ltd. now believes. The incident took place 8.3 kilometers (5.2 miles) from Alexandria beach in northern Egypt.

Emirates Integrated Telecommunications Co., the United Arab Emirates' second-biggest mobile-phone company, is working with the cable operators, Flag Telecom and SEA-ME-WE 4, to find out why the cables were cut and to determine when service can be restored.

The outage is a reminder that physical infrastructure, however mundane, underlies all of modern computing and communications. It's also a reminder that if your business or life depends on Internet-based communications, commerce and content, you need a diversity strategy. It costs more money. But so does inability to do your work.

Amazon Elastic Compute Cloud: Heavy Use

A growing computing architectural theme is the move of functions out of proprietary data centers and "into the cloud," a return in some ways to the days of time sharing as a computing architecture. So it is that 330,000 or so developers have registered to use Amazon Web Services, up more than 30,000 from the prior quarter.

And those users are driving traffic and compute cycles. Amazon Elastic Compute Cloud (EC2) and Amazon Simple Storage Service (S3) consumed more bandwidth in fourth quarter 2007 than was consumed in the same period by all of Amazon.com's global Web sites combined.

At some point, the availability of cloud computing resources is going to fundamentally alter the tradtional "build versus buy" equation that has had enterprises and other large entities building and maintaining their own data centers. At some point the computing framework used by smaller entities and individuals is going to change as well.

At some point, one has to wonder whether communications and computing, increasingly intertwined, might also be thought about in different ways.

To the extent that servers, air conditioning, power, space and communications are the underpinning for applications, and to the extent that enterprises and individuals typically only care about infrastructure to the extent that it enables use of applications, one is lead to ponder the notion of outsourcing of infrastructure.

To what extent must even a large provider "own" its own conduits, routes, physical media, servers and software of an infrastructure sort? To what extent can those things be sourced more extensively on a "buy" basis rather than a "build" basis? In how many more use cases will it make sense to source wholesale capabilities from other providers instead of building, owning and operating facilities?

To the extent that it is the "computing" that matters, not the "computers," one also might ask whether it is the "communications" rather than the "network" that matters.

Margin, Churn Improvement at 8x8

Revenues from Packet8 Virtual Office hosted business phone service now contribute 48 percent of total 8x8 revenues, up one percent from the previous quarter. Virtual Office revenue grew eight percent over the prior quarter. That's important given 8x8's intention to focus on business customers, even as it fills out its revenue with consumer customers.

In the consumer segment, revenue was flat, and declined by three percent year over year. So the consumer business appears stable.

During the December quarter, 8x8 gross margins were 65 percent, an improvement 8x8 attributes to improved scale. Overall service margins rose to 70 percent. Packet8 Virtual Office service margins increased to an all time high of 83 percent, an impressive figure rivaling the sort of return an efficient provider gets from far-simpler T1 services.

Broadband Buckets: Way to Avoid Packet Discrimination

Many years ago, wireless and wireline minutes of use were sold on a metered basis. These days voice and texting are sold by the bucket. There's now more experimentation with that sort of model for broadband access as well.

It might seem odd, but changing the way broadband access is priced at retail, using a model similar to wireless minutes of use and texting, might be beneficial for end users, not simply for Internet Service Providers.

The reason is that if a user wants to buy a bigger bucket to move more packets for peer-to-peer video, the user is happier and so is the provider, who is able to match revenue with use of network resources.

That's arguably a better solution that having ISPs deploy sniffing and packet inspection capabilities so they can inspect all packets (as happy as some solution providers would be to sell all that capability).

Since deep packet inspection has to impose some overhead and latency, the user's applications arguably should work better as well (also avoiding privacy concerns). If any user is found to be shipping around video bits in violation of copyright, there are other remedies.

That's the way enterprises and businesses buy bandwidth, by the way. They pay more money but have unrestricted right to use the bandwidth they've purchased. Pricing consumer access in the same way wireless text and voice now can be bought would allow users to make their own choices about what applications they want to use, and how much.

It isn't metered usage in any way more objectionable than buckets of minutes or texting are. And it might allow ISPs to avoid the DPI effort.
