A quick check of independent Internet-monitoring services appears to confirm the complaints. Here's a chart showing Syrian traffic to Google dropping off a cliff:
And here's the Web services provider Akamai's report:
All three sources show a steep drop in Syrian inbound and outbound Internet traffic beginning around 1:45 p.m. Eastern (6:45 p.m. GMT).

An ominous reason that Assad has cut off internet access might be because he is about ready to do something that he doesn't want reported on social networking or other websites. Given the pathetic response of the west to his use of chemical weapons, perhaps he is about to expand their use and doesn't want any living witnesses to confirm it.
