Data synchronization
Distributed systems depend on synchronization, but every approach has tradeoffs. From full copies to delta updates, how do you choose the right method?

Life on the Internet adoption curve
The technology adoption curve has not changed, our position on it has. As the Internet and BGP move into later stages of adoption, rapid growth is giving way to saturation, changing how we plan, invest, and operate.
ROA adoption barriers to practical planning tools: Reflections from ARIN 57
Guest Post: Even operators with strong BGP knowledge tend to create ROAs infrequently and may lack deep familiarity with their behaviour. ROOTBEER helps operators understand what to consider when creating ROAs.
Hunting stuck routes with the BGP Clock and the BGP Stuck Route Observatory
Guest Post: BGP stuck routes remain an important problem for network operators. To help bridge this visibility gap, Cisco ThousandEyes introduced a methodology for measuring the prevalence of stuck routes: The BGP Clock.
BGP Router ID structuring in IPv6 native networks
Guest Post: How to design and structure BGP Router IDs in IPv6-native networks.
Discovery of IPv6 router addresses using Subnet-Router Anycast addresses
Guest Post: Identifying active IPv6 addresses helps assess deployment, reveal gaps, and detect vulnerable devices. Subnet-Router Anycast (SRA) probing removes the need for prior knowledge of address allocation.
Ephemeral leaks and automated BGP route leak detection
Guest Post: Many BGP route leaks flagged by automated systems are short-lived artifacts of normal convergence. Doug Madory draws on Cloudflare Radar, RouteViews, and Jared Mauch’s leak detector to show how these ‘ephemeral leaks’ occur, why they rarely disrupt traffic, and why they still matter for routing security.
SCION: The overlay network for bankers
SCION has both supporters and critics, but it faces a major challenge: Replacing BGP while competing in an environment where network decisions are driven more by carrier costs than by strategic priorities.
Detecting and characterizing DDoS scrubbing from global BGP routing
Guest Post: Analysing public BGP data to characterize the real‑world behaviour of five major scrubbing services.
Noisy routers: Investigating the make-up of route collector data
Guest Post: An analysis of more than 80 billion updates reveals how ‘noisy’ BGP updates inflate MRT archives, bias measurements, and highlights the need for more careful interpretation of BGP data.
