CNN — Internet connections across Syria went down on Tuesday night, according to several global monitoring sites.
The Renesys Internet tracking company reported the loss of Syrian Internet connectivity around 9:45 p.m. local time. Google also reported that its services became inaccessible in Syria at that time.
The website for Syria's state-run news agency and several government websites were also down.
A CNN staffer in Damascus could not connect to the Internet. At one hotel, staffers said the Internet was down "in the hotel and all of Damascus."
"All types of communications; Internet, mobile, and land-line are not working in the capital, Damascus...in conjunction with a power outage in most parts of the capital," said a post on the Facebook page for the Syrian Revolution opposition activists group.
The cause of the apparent outage was unclear.
After a similar situation in November, U.S. Ambassador to Syria Robert Ford told CNN that Syria had shut down the Internet in the past.
"The Syrian government has been monitoring (the Internet) for years," he said. "They have been using the Internet with Iranian assistance to track opposition activists, arrest and kill them."
"That is the reason why our nonlethal assistance to the Syrian opposition, we put a special emphasis on communications equipment precisely to help the Syrian people tell the world what is going on inside Syria," he said.
