Washington: The website of the US National Security Agency was reportedly down for several hours as a result of an apparent technical glitch and not due to a speculated hack-attack .
The NSA said that its website was not accessible because of an internal error that occurred during a scheduled update, which will be resolved immediately.
The spy agency further clarified that the claims that the outage was caused by a distributed denial of service [DDoS] attack are not true, ABC News reports.
According to the report, the website was down for at least six hours and an agency spokesperson said that the agency`s internal, sensitive network was not compromised and no classified information was at risk.
However, one hacktivist group online claimed that they were responsible for bringing down the NSA site with a sophisticated DDoS attack.
The NSA has been long battling with the allegations of breaching public trust after revelations about the alleged secret surveillance programmes as exposed by whistleblower Edward Snowden.
