The internet access in Syria is reported to have restored following a nationwide blackout, which lasted for over 19 hours.

Web monitoring firm Renesys has reported that Internet was back in the country.

James Cowie of Renesys said, "Since 18:45 UTC on May 7th, Renesys hasn’t seen a flicker of activity."

"We haven’t been able to successfully send a ping or a traceroute to any host inside Syria. Government websites, universities, domain name servers, core infrastructure routers, banks, businesses, DSL customers, smartphones: all silent," Cowie said.

BBC said local state-run media had reported earlier that a fault in optical fibre cables was responsible for the blackout.

David Belson, of Akamai, told the BBC, "Our monitoring shows that Syria’s international internet connectivity is through at least four providers, and published submarine cable maps show connectivity through three active cables."

"As such, the failure of a single optical cable is unlikely to cause a complete internet outage for the country," Belson said.

In November 2012, Syria has also experienced an Internet shutdown, which lasted for three days.

In June 2011, a substantial part of the Internet was blocked in Syria due to protests against the country’s President Bashar Assad’s regime.
