The United Nations marked World Telecommunication and Information Society Day on 17 May 2026, highlighting the growing importance of digital technologies as critical lifelines that connect people to safety, essential services and one another.

The day was observed alongside the International Telecommunication Union (ITU), which stressed the need for secure, trusted and accessible digital infrastructure worldwide.

In a message issued for the occasion, António Guterres said that digital networks play a vital role during emergencies and disasters. He noted that communication systems carry early warnings, support first responders, and help clinics, classrooms and public services continue operating during crises.

However, he warned that major challenges remain. According to the United Nations Secretary-General, many communities still lack internet access, while critical systems remain vulnerable to cyberthreats and disinformation. He also highlighted the growing impact of climate emergencies and the widening AI divide, which disproportionately affect underserved populations.

Furthermore, Guterres called for greater investment in digital connectivity. He pointed to the importance of strengthening infrastructure, including seabed cables, satellite systems, local access networks, open standards and digital skills development.

The United Nations also urged governments, industry leaders and civil society organizations to work together to implement the Global Digital Compact, advance rights-based AI governance and improve international cooperation on digital resilience and cybersecurity.

In addition, Guterres described digital infrastructure as an essential public good that must be built to withstand future crises. He added that universal and secure digital lifelines can help communities prepare for, respond to and recover from emergencies more effectively.

The United Nations concluded that ensuring safe, inclusive and resilient connectivity remains critical as countries face rising cyber risks, climate-related disasters and increasing dependence on digital technologies worldwide.
