Recently I posted about South Korean cellcos launching unlimited LTE plans at the start of this month, which seemed unusual given efforts by cellcos in other markets to put an end to unlimited mobile data plans, which were unsustainable in the post-iPhone/phablet age.   Wondering if this was either the vanguard of a move back to unlimited data or a reflection of specific market circumstances, I put that question to Ovum analyst Nicole McCormick, who advised cellcos early on to avoid the unlimited data trap when pricing LTE.   Her answer – it’s a Korea thing.   "This is an idiosyncratic move based on a specific ...

If it seems like web sites have been slow to deal with the Heartbleed bug by revoking and reissuing certificates, turns out there’s a good reason for that: it’s costing them a fortune in bandwidth.   That’s according to CloudFlare, which recently went through the process of reissuing and revoking all of its customers' SSL certificates. In the process of doing so, it got a first-hand look of the effect such a procedure has on bandwidth demands.   As CloudFlare’s Matthew Prince explained in a blog post, the reason for the bandwidth spike has to do with the way a browser checks if ...

ITEM: South Korea’s three cellcos have escalated their LTE rivalry with unlimited LTE packages.   According to Korea JoongAng Daily, LG U+ is now offering two plans that include unlimited LTE data, as well as unlimited voice and text messaging. The same day, SK Telecom and KT launched similar unlimited LTE plans.   SK Telecom also launched a “commuter” plan that offers unlimited data specifically during morning and evening commuter times.   All three cellcos are also throwing in various amounts of multimedia content and services, such as HD video, music, navigation and cloud storage.   There is one catch: the “unlimited” part refers to ...

ITEM: Global Cloud Xchange – a.k.a. the carrier formerly known as Reliance Globalcom – is building a new Trans-Pacific cable from Tokyo to California that will offer terabit connectivity to customers.   According to the official announcement earlier this week, the Pacific Cloud Xchange (PCX) cable – scheduled to go into service next year – will be an 8,300km “four fiber pair system with initial design capacity per fiber pair at 100 x 100 Gbps using next generation coherent submarine fiber”, but Global Cloud Xchange CEO Bill Barney says it could be even bigger.   “We were initially looking at four fibers, but we ...
