With pitched fighting in Damascus, Al Jazeera reports that the Internet is down across Syria, and mobile phone services also disrupted in some areas. Syrian state TV denied the blackout is nationwide, but Renesys, a US-based network security firm that studies Net disruptions, said Syria has effectively disappeared from the Internet. There is some talk that the Net blackout may be due to insurgent attacks, but the regime seems to be conniving in it, at the very least. Recall that when Mubarak pulled the same stunt in January 2011, it proved to be the 10-day countdown to his overthrow.
