(CNN) How do you run a digital business when your country's president has shut down the internet?

Salim Azim Assani, who lives in Chad, is finding out the hard way after living under internet censorship for more than 365 days and counting.

Assani, 33, runs WenakLabs , a digital co-working space in the Chadian capital of N'Djamena and has resorted to using expensive Virtual Private Networks (VPNs) to circumvent the shutdown.

"It's absolutely necessary to use VPN and very often we find ourselves abroad using it and only realize that we don't need it elsewhere," Assani said.

A VPN acts as a secure tunnel between devices and the internet; it protects users from snooping and censorship and allows them to mask their location on the internet.

The social media blackout began in March 2018 after recommended reforms to the constitution that would allow President Idriss Deby to stay in power until 2033, when he will be 81

Deby has been at the helm since 1990 and had previously pledged to restore term limits before the country's 2016 elections.

The country's internet services was shutdown almost immediately after the planned reforms were announced.

Julie Owono, the Executive Director at Internet Without Borders (IWB) , a Paris-based non-profit organization advocating for freedom of expression on the internet told CNN, "Last year on March 28, we received various reports from our resources on the ground that access to WhatsApp was very difficult or just impossible in some places."

Owono believes the shutdown was introduced because videos of violent clashes among the Zaghawa tribe in northern Chad were being shared on WhatsApp, and the government took advantage of that to repress discontent among citizens.

Communal clashes are rife in Chad, a landlocked country in central Africa that is roughly the size of Texas. It's had a turbulent history of religious and ethnic conflict and intermittent civil war since it gained independence in 1960 from France.

Since March 2018, people in Chad have been unable to access sites such as WhatsApp, Viber, Facebook, and Twitter. It's not the first time in Chad either: a shutdown of the internet lasted for eight months in 2016 following a disputed presidential vote that secured a fifth term in office for Deby.

Internet shutdowns are frequently used by governments across Africa.

In 2019 alone, Sudan, Zimbabwe , and the Democratic Republic of Congo have all enforced a shutdown for various reasons.

The economics of censorship

Protests in the internet age often begin or become amplified on social media. Autocratic regimes in Africa shut down the internet to repress free speech and freedom of association during uprisings that challenge their leadership.

It's difficult to say if these measures are effective but they adversely affect the economy of these countries.

Internet shutdowns in 10 sub-Saharan African countries led to a deficit of more than $235 million from 2015 to 2017, according to a Collaboration of International ICT Policy in East and Southern Africa (CIPESA) report.

IWB estimates the shutdown has cost the Chadian economy at least $20 million since it began last March, and Assani, of WenakLabs, has been feeling the real-life impact.

"This situation slows down our work in terms of skills development and digital communication. It is clear that this is a strain on our economic growth," he said.

"The Chadian government needs to take advantage of the opportunities the internet offers for economic development and especially for young people," says Muhammad Sani Abdullahi , a former World Bank policy expert and current member of its Advisory Council on Citizen Engagement.

"For young people who constitute a greater chunk of the populace, reliance on the internet for daily functions has become a must, business, both small and large wouldn't be able to continue their everyday activities should the government keep the people cut out," Abdullahi said.

A lack of attention

If you're wondering why you're only just hearing about a country limiting internet access for more than a year, it is because Chad doesn't receive much attention in the international news media.

Beyond the trial and conviction of its former dictator Hissene Habre for crimes against humanity, Chad hardly ever finds itself in the spotlight.

Yet the lack of attention doesn't diminish its importance on the international stage.

Indeed Chad is an important ally of Western nations in the fight against terrorism, says John Campbell , a fellow at the Council for Foreign Relations and former US ambassador to Nigeria.

"Chad is important because of its physical location. It is part of the Lake Chad basin. It also borders on Sudan and Libya. It's literally right in the heart of a part of Africa where the security challenges are severe," Campbell said.

"The second point is that Chad for a long time has had an important security relationship with France. There are French military forces stationed in Chad and the Chadian military has received quite good training from them."

International pressure

Chad is also a member of the US-funded Trans-Sahara Counterterrorism Partnership , a coalition of north and west African countries fighting terrorism.

With such Western military allies, Owono says there would be international pressure on the Chadian government to restore social media access to its people.

But there has been a curious silence, at least publicly, from Western nations over what amounts to a violation of international law

According to the United Nations -- which Chad is a member of -- disconnecting people from the internet violates their rights as laid out in its Universal Declaration of Human Rights

Blocking the internet also means Chad is lagging behind on achieving Sustainable Development Goal 9c that aims to "significantly increase access to information and communications technology and strive to provide universal and affordable access to the internet in the least developed countries by 2020."

Internet Without Borders, Access Now and Utopie Nord-Sud submitted a joint report to the UN Human Rights Commission in 2018 on the state of freedom of expression in Chad but Owono says they have been left disappointed by the response so far.

A fundraiser to buy premium VPN access raised €2,000 ($2250) and Owono says her organization will purchase access for journalists, activists, and human rights defenders who are most in need of it.

Anger and revolt

Internet penetration in Chad was very low in the first place: according to Internet World Stats , only 5% or about 768,000 people in a country of more than 15 million used the internet in December 2017.

And the censorship means even fewer people now have access to social media.

The Committee to Protect Journalists and IWB are among many groups asking the Chadian government to restore internet to the central African nation.

A planned protest in Paris on January 19 was canceled due to the ongoing Yellow Vest protests in France. But a campaign on Twitter under the hashtag Maalla_Gatétou , meaning "why did you cut me off" in Chadian Arabic was launched eariler in the year.

A proposed meeting between activists and the government was scrapped after the Chadian authorities declined an invitation to dialogue from Owono's Internet Without Borders.

They had been hopeful in the weeks before as a similar tactic bore fruit when the Cameroonian government shut down the internet in 2017.

As the fight for a full restoration rages on, Assani of WenakLabs says he feels "a little bit of anger, revolt, and discouragement."

"It's as if the internet was a monster whose head had to be cut off," he said.

Asked if he had any hope of the censorship being lifted, Assani was to the point: "No, there is no hope."
