Global report warns of critical vulnerabilities in interconnected digital systems, calls for stronger resilience

A new joint report by the International Telecommunication Union (ITU), the United Nations Office for Disaster Risk Reduction (UNDRR), and Sciences Po has warned that the world’s increasingly interconnected digital infrastructure faces critical vulnerabilities that could trigger large-scale disruptions across essential services.

Titled “When digital systems fail: The hidden risks of our digital world,” the report maps potential risk scenarios across terrestrial, maritime, and space-based systems, highlighting how events such as solar storms, submarine cable cuts, satellite disruptions, and extreme weather could cascade into widespread digital failures.

The report cautions that such disruptions could impact critical sectors including healthcare, finance, energy, and emergency communications, potentially resulting in what experts describe as a “digital pandemic” if systemic risks are not addressed.

Speaking on the findings, ITU Secretary-General Doreen Bogdan-Martin emphasized the need to embed resilience into the core of digital systems, noting that risks affecting interconnected technologies must be understood as systemic rather than isolated events. She called for a fundamental rethink in how digital infrastructure is designed, protected, and governed.

UNDRR leadership also stressed that increasing reliance on digital systems means that natural hazards and other shocks can rapidly cascade across borders and sectors, amplifying their impact. The report highlights that digital infrastructure must be treated as critical infrastructure requiring resilience planning on par with physical systems.

The study outlines multiple scenarios illustrating the fragility of modern digital ecosystems. These include solar storms capable of disabling satellites and energy grids, extreme heat affecting data centre operations and communications networks, and natural disasters such as earthquakes severing internet connectivity for extended periods.

It also identifies a growing societal vulnerability: the erosion of analogue backup systems and offline capabilities, which limits recovery options when digital systems fail.

Experts contributing to the report, including academics and policymakers, emphasized that addressing these risks requires cross-disciplinary collaboration and evidence-based policy approaches to strengthen global digital resilience.

The report calls for urgent action from governments, industry, and civil society, recommending six priority areas including improved risk mapping, modernized regulatory frameworks, strengthened international coordination, and enhanced fallback systems.

It further urges investment in societal preparedness and trust-building mechanisms to ensure communities can withstand and recover from digital disruptions.

The findings are based on contributions from experts across 12 countries and represent a consolidated effort by international organizations, national authorities, academia, and the private sector to better understand and address systemic risks in the digital age.
