    Forward Proxy vs Reverse Proxy ✨

    Forward proxies sit between clients and the internet, filtering requests and providing anonymity, while reverse proxies sit between the internet and servers, handling load balancing, security, and caching. Forward proxies require client configuration and are commonly used in corporate networks for access control, whereas reverse proxies are transparent to clients and provide server-side benefits like TLS termination, DDoS protection, and traffic distribution across multiple servers.

    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.

    What Is Latency

    Network latency refers to the round-trip time required for data to travel from its source to destination and back. Understanding latency is crucial for developers working on performance optimization and network-dependent applications.
