How to turn off the Internet in Egypt
As is known, since January 28, there is practically no Internet in Egypt. Only one Internet provider, the Noor Group, remained in the country, which serves the stock exchange and a number of government organizations.
According to the schedule from Renesys, it is clear that the largest Egyptian subnets were disconnected individually.
Apparently, the disconnections were made manually, by a phone call - each provider was called in turns and they voluntarily disconnected one after the other. Judging by the schedule, calls were received for thirteen minutes on January 28 from 00:12:43 to 00:25:10 local time (UTC + 2). Soon, about 3,500 Egyptian BGP routes stopped working. Simultaneously with the Internet , mobile communication was turned off .

Cairo in the same time zone as Kiev and Minsk. The country is currently offline for almost 37 hours.
According to experts, this is an unprecedented event in the history of the Internet, which cannot be compared with selective filtering in Tunisia and Iran. For the first time, such a large country (79 million inhabitants) with such a developed computer infrastructure turned out to be completely disconnected from international communication channels. Egypt is one of the most technologically advanced states in the Middle East, not to mention Africa. Critical backbones from Europe to Asia pass through the country. Fortunately, they still remain intact.
In America, they are now discussing whether the government should have a “switch” that will automatically turn off all routers if necessary. In practice, in order to disconnect a country from the Internet, no special technological delights are needed, it is enough to know the necessary phone numbers.
