Technical problems at Google are preventing an unknown number of people from using its Internet search engine, e-mail and other services, according to AP. In a today post on its Web site, the Mountain View-based company reports that a «small subset of users» hasn't been able to get into their e-mail accounts. Without elaborating, Google says the e-mail trouble might be affecting other services as well. Multiple messages posted on Twitter, a popular information-sharing forum, indicate that people all over the world are having trouble with the Google search engine and e-mail. But other Twitter users say their Google services have been running smoothly. Google says the company is working to fix the problems.
