This Week in Net: Cloudflare's farewell to Railgun (and its relevance)

This Week in Net: Cloudflare's farewell to Railgun (and its relevance) Welcome to our weekly review of stories from our blog and other sources, covering a range of topics from product announcements, tools and features to disruptions on the Internet. João Tomé is joined by our CTO, John Graham-Cumming.

In this week's program, we discuss our CEO, Matthew Prince, visiting Lisbon, Portugal (which includes a picnic). We delve into the Regional Tiered Cache, which offers an additional layer of caching for Enterprise customers with a global traffic footprint, enabling faster content delivery by reducing network latency.

However, the main focus is bidding farewell to Railgun, a web optimization technique launched by Cloudflare ten years ago. We explore why it was developed by John Graham-Cumming, its relevance, and the decision to deprecate it in January 2024.

Lastly, we provide a guide on how to perform dynamic data collection using Zaraz Worker Variables (Cloudflare Zaraz being our server-side third-party manager designed for speed, privacy, and security).
