In a major cyber security breach, Antrix, the website of Indian Space Research Organisation's (ISRO) commercial arm, was hacked on the afternoon of 12 July.

This comes two days after ISRO launched five of its heaviest British satellites from its Polar Satellite Launch Vehicle (PSLV) in Sriharikota, Andhra Pradesh.

ISRO has confirmed that there was a problem with the homepage.

The site has now been recovered and shows "This Site is Under Construction. Come Back Soon."
