Twitter appears down across much of planet
London: Micro-blogging site Twitter went down affecting users on multiple continents just minutes after Google restored its GTalk service, which had suffered massive outage on Thursday.
The company acknowledged the problem, saying in a statement that its engineers are "currently working to resolve the issue," although it didn't go into any further detail.
Users reported outages or sluggishness in trying to access Twitter from countries in North America, Europe, Asia, the Middle East, and Africa.
The Olympics are expected to bring an unprecedented surge of activity by sports fans on social networking sites such as Twitter.
At the recent European Championship final, users fired off more than 15,000 tweets per second, setting a sports-related record for the site.
