The teenagers who wired Romania

In the late '90s, in daring feats of DIY networking on rooftops across Romania’s capital, Bucharest, teenagers are stringing computer cables between tower blocks to share an internet connection. This guerilla infrastructure starts out scrappy, but it sprawls into an impressive improvised network that catches the attention of telecom giants. Told by those who built it, this is the extraordinary story of how a homemade system became the backbone of a city - a reflection of what the internet was meant to be and what it became.
