Google is suffering a worldwide outage, with failures reported across the company's services, including Gmail, Google Calendar, and YouTube.
Beginning at about 11.50 am GMT, the outages appear to have affected the vast majority of the company's services, apart from Google search, which is still operating mostly unaffected.
Despite the universal nature of the outages, the company's automated systems reported no problems for any services for the first 30 minutes of the blackout, across consumer-facing and cloud tools for developers.
