Amid mounting protests in the streets of Cairo, Twitter has been blocked in Egypt.

Demonstrations that were organized via Facebook and Twitter brought thousands into the streets to speak out against failing economic policies, government corruption, and to call for an end of the nearly 30-year reign of President Hosni Mubarak.

The ban on Twitter has gradually extended to various aspects of the social network. First, both the mobile site and the physical site were blocked. Then it extended to third-party clients and applications. Currently, Web proxies are the only way to access Twitter.

Other reports have said that Twitter has been blocked by mobile carriers. One provider, Vodafone, has denied the allegations, suggesting that the issue came from elsewhere.

"We didn't block twitter – it's a problem all over Egypt and we are waiting for a solution," @VodafoneEgypt tweeted.

A Twitter spokesperson would not confirm the ban, but pointed to the Herdict Report, which shows where Twitter is inaccessible. @HerdictReport confirmed the outage. According to the report, Twitter "has been reported inaccessible six times in Egypt."

"Twitter is blocked in Egypt," tweeted @ircpresident.

Protests in Egypt were inspired in part by the uprising staged in Tunisia that ousted autocratic President Zine el-Abidine Ben Ali earlier this month.

"We Are All Ali Khaled Said," a Facebook group named after an activist who was reportedly beaten to death by police, had more than 90,000 users signed up to protest on Tuesday morning, CNN said. However, Facebook remains unaffected at this point.
