Episode Details

In 1995, Tim Berners-Lee identified a critical problem: every website lived on a single server in a single city, making physical geography the web's biggest bottleneck. Two MIT researchers answered with radical simplicity—just make copies. This is the story of how edge servers and content delivery networks solved the broken web by scattering content across the globe, and why "making copies is easy" became the field's most important truth. 00:00 - The World-Wide Wait: The Problem 02:30 - Tim Berners-Lee Issues a Challenge 05:00 - Tom Leaton and Danny Lewin's Solution 08:15 - How CDNs Work: Edge Servers and Points of Presence 12:45 - Making Copies: The Simple Truth 16:30 - Scaling the Global Network --- Sources & further reading: • Danny Lewin — Slate — "The First Victim on 9/11 and an Architect of the Internet": https://slate.com/technology/2015/09/danny-lewin-the-first-victim-on-9-11-and-an-architect-of-the-internet.html • Fastly outage analysis — ThousandEyes — "Inside the Fastly Outage": https://www.thousandeyes.com/blog/inside-the-fastly-outage-analysis-and-lessons-learned • Cloudflare gatekeeper debate — Reason — "Cloudflare Can Cancel Service to Terrible Websites Like Kiwi Farms.
