This post is part of our special coverage of Egypt Protests 2011 .
Over the past few days, as protesting Egyptians have utilized social media tools for organizing and disseminating information, they've also come across numerous obstacles to access: On January 25, Twitter was reportedly blocked , with Facebook following the next day . By the 27th, access to both sites was sporadic.
At around 1:00 am in Cairo on Friday, January 28–a day of planned protests–reports began to trickle in that the Internet had become inaccessible to Egyptians in Cairo and Alexandria. A few minutes later, @iman_said tweeted :
we should be prepared for total mobile phone blackout tomorrow also (or at least in protest hotspots) #Jan25 
Those working to contact friends and family in Egypt expressed frustration and concern over Twitter. @alaa explained :
cell phones still working in egypt that's how I'm staying in touch, but service spotty in areas
Despite the block, it appears that a few remaining Egyptians are still tweeting in hopes of getting news out to the world. In light of the blackout, Global Voices will attempt to report from phone calls and other communications over the course of the next few days.
