    A complete guide to HTTP caching

    HTTP caching reduces latency, server load, and infrastructure costs by storing responses at multiple layers—browsers, CDNs, proxies, and application caches. The guide explains how Cache-Control directives (max-age, s-maxage, no-cache, no-store, stale-while-revalidate), validators (ETag, Last-Modified), and headers like Vary control freshness and revalidation. It covers common misconceptions (no-cache doesn't mean "don't cache"), freshness calculations, practical recipes for static assets, HTML, APIs, and authenticated content, plus browser behaviors like BFCache and speculation rules. A detailed Cloudflare section addresses CDN-specific defaults, edge cache TTLs, cache key normalization, and cache tags for event-driven purging.

    From .com to .anything: introducing Top-Level Domain (TLD) insights on Cloudflare Radar

    Cloudflare Radar launched a new Top-Level Domain (TLD) insights page that provides comprehensive data on TLD popularity, traffic patterns, and security metrics. The page uses DNS Magnitude—a metric measuring how many unique networks query domains within a TLD—to rank over 2,500 TLDs. Surprisingly, .su (Soviet Union's legacy TLD) tops the ranking due to queries from a popular online game. Individual TLD pages offer detailed information including DNSSEC support, RDAP availability, DNS query volumes, certificate issuance data, and geographic distribution. The feature extends existing DNS insights to all delegated TLDs and integrates with Cloudflare Registrar for domain registration. All data is accessible via API and the Radar Data Explorer.

    Is everyone switching to MoQ from WebRTC?

    Analysis of Media over QUIC (MoQ) adoption claims versus reality, using Chrome usage metrics to debunk assertions that developers are switching from WebRTC. Chrome data shows WebTransport usage remains minimal (0.035% peak vs WebRTC's stable 0.35%), with multiple failed experiments over five years. Addresses misconceptions about WebRTC architecture, noting that server-based deployments (SFUs/MCUs) have been standard for years, not peer-to-peer full mesh. Concludes that despite marketing claims, no successful large-scale migration from WebRTC to MoQ has occurred yet.

    The whole internet was down... again...

    Recent major outages from Cloudflare and AWS exposed critical vulnerabilities in modern internet infrastructure. While cloud services promised decentralization and resilience, the industry has consolidated around a few vendors using default configurations. Cloudflare's outage was caused by an oversized feature file in their Bot Manager component. The real issue isn't the outages themselves, but the illusion of resilience created by cloud-native tools while actually centralizing failure points. Modern developers increasingly lack the knowledge to build systems that gracefully handle failures, relying instead on configuration wizards and AI assistance.

    Cloudflare 1.1.1.1 Incident on July 14, 2025

    Cloudflare's 1.1.1.1 DNS resolver experienced a 62-minute global outage on July 14, 2025, caused by an internal configuration error that inadvertently linked the resolver's IP prefixes to a non-production Data Localization Suite service. The issue originated from a dormant misconfiguration made on June 6, which was triggered when changes were made to the test service on July 14, causing BGP route withdrawals globally. The outage affected most DNS resolution methods except DNS-over-HTTPS traffic using the cloudflare-dns.com domain. Cloudflare is addressing the root cause by deprecating legacy systems and implementing staged deployment methodologies.
