Google stocks were up today, following news that the tech giant is making investments in an England technology community center and major expansion of its Internet infrastructure in Asia.

Business Insider’s “The Google Investor” reported “shares of Google were up in early trading but lost ground along with the rest of the tech tape by midday” on Thursday.Among the Mountain View, Calif.-based company’s announcements is this report that says Google plans to open a multimillion-pound “technology community center” in London's East End, as part of the government’s plans to create a Tech City in the capital.

“The seven-floor building will act as a shared space for the growing cluster of internet companies based in the heart of London's so-called “Silicon Roundabout.” Google will take on more than 25,000 square feet of office space until at least 2022,” Business Insider said.

Google also announced this week it has acquired land in Hong Kong, Taiwan and Singapore to build data centers in these three locations, PC World reported.

Taj Meadows, the company’s policy communications manager for Asia Pacific, told PC World the data centers will be the “first Google proprietary data centers in Asia,” and will be fully owned and operated by the company.

And earlier this week, Google Director of Green Business Operations Rick Needham announced a new $75 million investment to create an initial fund with Clean Power Finance that will help up to 3,000 homeowners go solar. 

In other Google news, the company is under the microscope of federal justice officials who are more closely reviewing the tech giant’s potential $12.5 billion acquisition of cellphone maker Motorola Mobility, TechZone 360 reported.

According to a filing with the U.S. Securities and Exchange Commission, Motorola Mobility Holdings and Google received a request for “additional information and documentary material” from the Antitrust Division of U.S. Department of Justice regarding the proposed merger between the companies.

“The companies intend to cooperate fully and respond expeditiously to the DOJ,” the SEC report said. The transaction is currently expected to close by the end of 2011 or in early 2012, according to the Sept. 28 SEC filing.
