UPDATE (2013-09-27 11:28 UTC):
I heard from what I consider a reliable source that the ISPs in Sudan 
were ordered to "shutdown the Internet".

The data we collected supports that: During the disruption described 
above a large number of networks were not globally visible anymore while 
a much smaller footprint of address space remained. Most Autonomous 
Systems (ASes) did not disappear completely from the global routing 
tables we collect, so possibly these ISPs mostly kept their 
international connectivity and core infrastructure running, while not 
providing Internet services to their end-users. Our RIPE Atlas 
measurements also support this, because the vantage point we have in 
SudREN that retained Internet connectivity seems to be close to their 
core infrastructure. With the data collected it's not possible to see if 
the users connected via SudREN had Internet access or not.
