Internet access in Egypt appears to have returned to normal, according to firms measuring traffic levels in the country.
Facebook and Twitter are now available and the four major Egyptian internet service providers are back in business.
They all had services cut last week, following mass protests against President Hosni Mubarak.
Net measurement firm Renesys said there were no traffic blocks in place any more.
"We confirm that Facebook and Twitter are up and available inside Egypt," it said in its blog.
The government crackdown on net services left millions of Egyptians without access.
But Egyptians quickly found ways around the blocks and on 1 February Google introduced a "speak-to-tweet" service which allowed people to connect to Twitter via the telephone.
Other traffic monitoring firms, including Arbor Networks, confirmed that net access was returning to normal.
