Exam Shutdowns Now Top Cause of Internet Outages

For years the top cause of major internet outages was mundane: power failures. A new review of Q2 2026 disruptions flips that, finding that deliberate, government-ordered internet shutdowns tied to national exams have overtaken power as the single largest cause of significant outages. The change is not technical, it is political. Whole countries are now switching off connectivity for millions of people to stop cheating on school and university exams, turning the internet into something a government toggles on schedule.

• Q2 2026 tracking recorded around 25 significant disruptions, with exam-related shutdowns becoming the leading category, ahead of power outages.
• These are intentional outages: authorities cut mobile data or full connectivity for hours during exam windows to prevent cheating.
• The shift marks a move from accidental disruptions (power, fiber cuts) to deliberate ones (shutdowns, conflict).
• Earlier in 2026, disruptions also came from conflict, including physical strikes on data-center infrastructure, underscoring how fragile connectivity has become.

Why would a government switch off the internet for an exam?

To stop organized cheating. Several countries, particularly across parts of the Middle East, Africa and South Asia, have adopted internet shutdowns as a blunt anti-cheating tool during high-stakes national exams, cutting mobile data or full connectivity during the hours a test is administered. The logic is that if answer keys and messaging apps go dark, leaks and coordinated cheating become harder. It is crude and effective at that narrow goal, and it treats nationwide connectivity as an acceptable thing to sacrifice for exam integrity.

What is the real cost of these shutdowns?

Enormous and largely unmeasured in the moment. When a country goes offline for even a few hours, everything that depends on connectivity stops: card payments, ride-hailing, deliveries, hospital systems, remote work, and every small business that sells online. Digital-rights groups have long documented that shutdowns cost economies far more than the exam problem they aim to solve, and they set a dangerous precedent, normalizing the idea that a government can and should flip the internet off when it finds connectivity inconvenient. Today it is exams; the same switch works for protests.

How is this different from a normal outage?

Intent. A power failure or a fiber cut is a system breaking; a shutdown is a system working as ordered. That distinction matters because the fixes are completely different. You cannot engineer your way around a deliberate shutdown with better hardware or redundancy; the disruption is imposed at the network's policy layer by the entity that controls it. The trend line, from accidental to intentional as the dominant cause, tells you the internet's biggest reliability risk in some regions is no longer technical resilience but political will.

Is anything pushing back?

Yes, though unevenly. Circumvention tools, satellite connectivity, and cross-border mesh approaches give individuals partial routes around shutdowns, and international pressure occasionally raises the cost of ordering one. But none of these neutralizes a determined state, and the fact that exam shutdowns have become routine enough to top an outage chart suggests the deterrents are weak. The more durable fix is political: making shutdowns diplomatically expensive and legally constrained, which is slow work against governments that see the switch as a feature.

Our take

An outage chart where the top cause is a policy, not a failure, is a quietly alarming document. It means the biggest thing standing between millions of people and the internet is a government's willingness to leave it on. Exam shutdowns feel almost reasonable framed as anti-cheating, which is exactly why they are effective as a normalizing wedge: they make the off switch routine. Power failures get fixed with better grids; deliberate shutdowns only get fixed when turning off a nation's internet carries a real cost. Right now, for too many governments, it does not.

What can affected people and businesses actually do?

Not much to prevent a shutdown, but plenty to soften it. For individuals, the practical hedges are the same ones used against censorship: keep a circumvention tool configured before you need it, and where available, satellite or cross-border connectivity offers a partial route around a national blackout. For businesses that operate in shutdown-prone regions, the resilient move is to assume connectivity is not guaranteed and design around it, offline-first workflows, cached data, and payment fallbacks that do not die the moment the network does. None of this neutralizes a determined state, and that is the uncomfortable truth: a deliberate shutdown is imposed at a layer ordinary users cannot reach. The durable fix is political rather than technical, which is exactly why these outages are harder to solve than a downed fiber line. You cannot engineer around a decision.
