Guest Post: A major CDN reduced its median latency by more than half during study into use of Bidirectional Anycast/Unicast Probing.
Guest Post: Good, fast, cheap — pick two. This has been a fundamental rule of network operations since the beginning. Or so we thought.
Guest Post: Emir Beganović investigates commercial CDN performance using RIPE Atlas.
Guest Post: Measuring latency data provides a powerful insight into any working network.
Guest Post: DNS-over-TLS provides an opportunity to improve query latency compared to UDP.
Guest Post: Coupled with an additional two-bit signal, the Valid Edge Counter, the QUIC spin bit can provide a higher resolution of latency trouble spots in a network.
Guest Post: Russ White reminds us why latency and jitter are more of a killer for application performance than lack of bandwidth.
Guest Post: What’s the source of latency on the Internet, and how can it be reduced?
Guest Post: New research studies the relationship between latency and anycast deployment of four Root DNS servers (C, F, K and L) to determine how many anycast sites are required for good latency.
Guest Post: Spreading domains used for nameservers may be best practice for some but may increase latency at the resolver.
