Knowledge becoming invisible
Public knowledge also depends on infrastructure that remains reachable, searchable and maintainable over time.
Public memory needs durable access
Domains, hosting and open standards as conditions for continuity
Over the years, all2all has repeatedly encountered situations where valuable public knowledge slowly became difficult to access, or disappeared entirely.
A social association may spend years building expertise in street work, publishing reports, documenting field experience and creating collective knowledge intended for public benefit. Yet when this material gradually moves onto closed social media platforms, it becomes difficult to search, difficult to cite and eventually almost invisible.
In other cases, organisations end their activity while their digital archives still retain clear historical, social or political value. When a movement, association or cultural initiative loses its domain name, hosting or technical maintenance, years of documents, debates, publications and public positions can suddenly vanish together with the infrastructure that carried them.
What disappears is often not only a website, but part of a collective memory.
These situations raise broader questions about digital continuity, open standards and long-term accessibility of public knowledge, questions that also form the background of projects such as Tango Time Travel.
