Solar PV for Internet resilience (Part 1): Designing your system
Guest Post: Solar photovoltaics and battery storage can provide reliable power for network infrastructure, even in remote locations. Here’s what’s good to know before selecting equipment.
Same place, different view: How VPNs shape what we learn about the Internet
Guest Post: A study found that changing VPN providers can change where web traffic appears to be served, affecting conclusions about domestic infrastructure, cross-border traffic, and data localization.
The EVPN trust challenge: How to detect and contain internal MAC hijacks
Guest Post: EVPN MAC mobility enables seamless workload movement, but it can also amplify the impact of MAC spoofing. A forged MAC address can redirect traffic across the fabric through BGP, making access-layer controls, route-reflector visibility, and MAC-move monitoring critical defences.
Turning IPv6 tunnels into programmable delay lines for pulsing DoS
Guest Post: TED shows how permissive tunnel decapsulation and inconsistent IPv6 Extension Header handling can focus low-rate traffic into short, high-rate bursts.
Being connected is not enough: Territorial inequalities in fixed-Internet access and performance
Guest Post: High aggregate Internet penetration can mask significant territorial inequalities. Using the Dominican Republic as a case study, this analysis shows that access and network performance vary widely across provinces, highlighting why the digital divide is about more than simply being connected.
Seven years of IPv6 in production: Lessons from one million broadband subscribers
Guest Post: IPv6 deployment is often described as a protocol upgrade. In reality, operating IPv6 at broadband scale is a test of subscriber management, DHCP, CPE interoperability, observability, and operational processes. Over seven years, WorldLink Communications grew to more than one million dual-stack subscribers, with around 70% of traffic now carried over IPv6. Here are the lessons that mattered most.
Is RPKI becoming harmful to BGP stability?
Guest Post: Could the growing deployment of RPKI become a threat to routing stability? This study analyses more than 11 years of RPKI and BGP data, measuring how much routing activity can be associated with RPKI-related changes.
Thou shall not pass: Gatekeeping outbound TLS connections
Guest Post: To quantify how closely guideline recommendations align with real-world TLS deployments, we collected over 50 million TLS handshakes during two weeks from our research institution.
Latest BGP hijack targets hosting software vendor
Guest Post: An analysis of the BGP hijack against Softaculous that enabled an attacker to obtain a fraudulent TLS certificate and distribute a malicious Virtualizor update.
