Google Burns Down, Twitter Knows First!
The blaze broke out on the roof patio of the company's London offices at lunchtime, the fire brigade said.
Around 5,000 Google staff and employees from other firms based in the six-floor building were evacuated.
Within minutes nearby workers had posted pictures of the blaze on the social networking website Twitter.
A spokesman from Google said: 'We have free food for staff at our offices and today was a barbecue day. We were having a barbecue on the patio where the fire started, but we're waiting to hear from the firefighters whether the two are linked.'
