"How Mubarak shut down Egypt's internet

EPITAPHS for the Mubarak government all note that the mobilising
power of the internet was one of the Egyptian opposition's most
potent weapons. But quickly lost in the swirl of revolution was the
government's ferocious counter-attack, a dark achievement that many
had thought impossible in the age of global connectedness.
In a few minutes just after midnight on January 28, a technologically
advanced, densely wired country with more than 20 million people
online was essentially severed from the internet.
The blackout was lifted after just five days, and it did not save
President Hosni Mubarak. But it has mesmerised the worldwide
technical community and raised concerns that with unrest coursing
through the Middle East, other autocratic governments may also
possess what is essentially a kill switch for the internet.
Because the internet's legendary robustness and ability to route
around blockages are part of its basic design, even the world's most
renowned network and telecommunications engineers had been perplexed
the Mubarak government succeeded in pulling off the manoeuvre.
Engineers have now worked out that the government exploited a
combination of vulnerabilities in the national infrastructure - the
main one being that the Egyptian government owns the pipelines that
carry information across the country and into the world.
Internet experts say similar arrangements are more common in
authoritarian countries than is generally recognised. In Syria, for
example, the Syrian Telecommunications Establishment dominates the
infrastructure, and the bulk of the international traffic flows
through a single pipeline to Cyprus. Jordan, Qatar, Oman, Saudi
Arabia and other Middle Eastern countries have the same sort of
dominant, state-controlled carrier.
Over the past several days, activists in Bahrain and Iran say they
have seen strong evidence of severe internet slowdowns amid protests
there. Concerns over the potential for a government shutdown are
particularly high in North African countries, most of which rely on a
just a small number of fibre-optic lines for most of their
international internet traffic.
The government's attack, in which it shut down its portals, achieved
a double knockout. It cut off Egypt from the outside world and left
its internal systems in a sort of comatose state: servers, cables and
fibre-optic lines were largely up and running but were too confused
or crippled to carry information save a dribble of local email
traffic and domestic websites whose internet circuitry somehow
remained accessible."

Our truest response to the irrationality of the world is to paint or
sing or write, for only in such response do we find truth.
