Alibaba Cloud to launch London region

China’s favorite e-commerce giant Alibaba is planning the launch of a cloud region in London, two years after entering the European market with a data center in Frankfurt.

The move was not highly publicized; the company merely updated its website to advertise the future availability zones in the UK and an unspecified ‘Launch Date,’ offering early bird plans and free services to its potential customers.

Among these are three types of elastic compute services from low to high performance web servers, as well as a database hosting service, ApsaraDB for RDS.

It is unclear whether the company is building its own data center in the UK, and the information on its site – promising two nines of availability, dual availability zones and other generic data center characteristics such as CCTV, fiber diversity and 24/7 on-site engineers – gives little clue as to where it could be leasing the space.

Zayo is continuing to build Fiber in existing markets

It is good to see Zayo's commitment to continue invest and buildout fiber.

Dave Jones, EVP of dark fiber services for Zayo, told FierceTelecom that while the service provider will look for opportunities to grow its fiber network into new markets, enhancing existing builds allows it to gain new contracts with current customers, but also new customers that are along the path of the fiber.

“We’re continuing to look at opportunities to grow the network in new markets, but probably the bigger focus is on doubling down and getting greater depth in our existing markets,” Jones said. “With the majority of our existing markets being NFL cities and smaller markets, we’re going deep in each markets and leveraging those investments.”

Jones added that while it’s not ruling out new builds, “the focus has shifted now that we have these good footprints in place or being deployed over the next few years it creates a lot of opportunities for us.”

The service provider continues to see growing interest in dark fiber from a host of customer sets, including a mix of wireless operators, and increasingly school districts and health care providers. Source: FierceTelecom Sept 14, 2016
