Ecdysis: Rust Library for Zero‑Downtime Graceful Restarts

🔁 ecdysis is a Cloudflare open-source Rust library that enables graceful process restarts without dropping live connections or refusing new connections. It uses a fork-then-exec model with inherited listening sockets and a readiness handshake so the new process can initialize safely. The design provides crash safety during upgrades and prevents gaps where the kernel would refuse connections. The library integrates with Tokio and systemd and has been production-proven since 2021, saving millions of requests across Cloudflare’s global network.

High-Temperature Superconductors for Datacenter Power

⚡Microsoft is evaluating high-temperature superconductors (HTS) to improve datacenter power delivery, reduce transmission losses, and increase capacity within compact footprints. HTS cables, when maintained at cryogenic temperatures, carry electricity with near-zero resistance, enabling smaller, lighter cabling that generates negligible heat and avoids voltage drops. By partnering with manufacturers and system integrators, Microsoft plans pilots of rack-level HTS architectures and aims to rethink traditional power designs to support AI-era workloads.

CISA Guidance: Barriers to Secure OT Communication

🔒 CISA released guidance that examines why legacy industrial protocols are often insecure-by-design and why available protections are not widely adopted. Developed with OT equipment manufacturers and standards bodies, the document reports findings from interviews with asset owners and operators about motivations to secure communication and barriers they face. The guidance identifies practical, operational, and technical obstacles and offers recommendations for owners and operators and manufacturers to drive more usable, sustainable security capabilities.

CISA Guide Helps Critical Infrastructure Adopt Secure OT

🔒 CISA released Barriers to Secure OT Communications: Why Johnny Can’t Authenticate to help operational technology (OT) owners, operators, integrators, and manufacturers adopt more secure communications. Based on interviews with stakeholders across Water and Wastewater, Transportation, Chemical, Energy, and Food and Agriculture sectors, the guide explains why insecure legacy industrial protocols persist and how threat actors can impersonate devices or alter messages. It identifies practical barriers—cost and complexity, latency and bandwidth, inspection issues from encryption, and interoperability with legacy products—and offers actionable recommendations to reduce friction and improve usability when procuring, deploying, and maintaining secure OT communications.

CISA Orders Removal of Unsupported Edge Devices Nationwide

🔒 CISA ordered federal agencies to remove edge devices that no longer receive vendor security updates and to strengthen lifecycle management within 12–18 months. Directive 26-02 requires agencies to catalog devices, update supported software immediately, report end-of-support items in three months, and decommission listed devices in 12 months and others in 18 months. CISA published an end-of-support edge device list and highlighted routers, firewalls, load balancers, wireless access points and IoT edge gear as high-risk targets for exploitation.

CISA directs removal of unsupported federal edge devices

🔒 CISA has ordered Federal Civilian Executive Branch agencies to inventory, update where possible, and remove all end-of-support edge devices—firewalls, routers, VPN gateways, load balancers, and other network security appliances—within an 18-month timeline. Agencies must report inventories within three months and begin removals within 12 months. CISA warned unsupported devices represent a substantial and constant threat and urged private sector adoption of similar measures.

CISA Orders Federal Agencies to Replace EOL Edge Devices

⚠️ CISA has issued BOD 26-02 requiring U.S. federal agencies to identify and remove end-of-life (EOL) network edge devices such as routers, firewalls, and switches that no longer receive security updates. Agencies must inventory devices on CISA's end-of-support list within three months, decommission pre-directive EOL devices within 12 months, and replace all identified EOL edge equipment within 18 months. The directive also requires agencies to implement continuous discovery processes within 24 months and encourages non-federal organizations to follow CISA's guidance to mitigate exploitation risks.

Cloud Outages Ripple Through Identity and Operations

🔐 Recent large-scale cloud outages affecting providers like AWS, Azure, and Cloudflare have shown how failures in shared infrastructure can incapacitate identity flows and halt business-critical systems. Even when an identity provider remains operational, failures in datastores, DNS, control planes, or load balancers can block authentication and authorization. Organizations should deliberately design resilience—using multi-cloud or controlled on-prem options and predictable degraded modes such as cached attributes or precomputed decisions—to avoid total access collapse.

Serverless File Integrity Monitoring with AWS Tools

🔒 This post demonstrates a serverless file integrity monitoring (FIM) pattern using AWS Systems Manager Inventory, Amazon S3, Lambda, and Amazon Security Lake. It collects file metadata from EC2 instances, exports versioned inventory objects to S3, and uses S3 Put events to trigger a Lambda that compares current and previous inventory versions to detect created, modified, or deleted files. When unauthorized changes are found, the function generates ASFF findings in AWS Security Hub, which Security Lake ingests and normalizes for query and visualization via Athena, QuickSight, or OpenSearch.

Cloudflare IPv6 route leak from router misconfiguration

⚠️ Cloudflare disclosed that a policy misconfiguration on a router caused a 25-minute Border Gateway Protocol (BGP) route leak for IPv6 traffic on January 22, producing congestion, packet loss, and roughly 12 Gbps of dropped traffic. The change removed specific prefix filters and made export rules overly permissive, redistributing internal IPv6 routes externally from Miami. Engineers detected and manually reverted the change, paused automation, and restored normal operations within 25 minutes. Cloudflare says it will add stricter export safeguards, CI/CD policy checks, improved detection, and promote RPKI ASPA adoption.

January 22, 2026 IPv6 BGP Route Leak from Miami Data Center

⚠️On January 22, 2026, an automated routing policy change caused Cloudflare to unintentionally advertise IPv6 routes from a Miami router for 25 minutes. The misconfiguration accepted internal IBGP routes and redistributed them to peers and transit providers, funneling non-Cloudflare traffic into Miami and causing congestion, elevated packet loss, and higher latency on backbone links. Firewall filters on the router discarded around 12 Gbps of ingress traffic for those non-downstream prefixes. Cloudflare paused automation, reverted the change, restored normal operation, and apologized to affected users, customers, and external networks.

Unencrypted TETRA Radio Leaves German Critical Sites Exposed

⚠️ Many German critical infrastructure organizations are transmitting over unencrypted digital radio, creating an easily exploitable interception vector. Wirtschaftswoche reports that prisons, airports and energy providers are operating TETRA networks without encryption—often citing cost reasons—while police networks remain multi-layer encrypted. AG Kritis calls the situation a security-policy disgrace, warning that a laptop, free software and modest technical skill are sufficient to eavesdrop and capture confidential information, potentially endangering supply security and lives.

How Cloudflare Workers Power Our Maintenance Scheduler

🧠 Cloudflare built a centralized maintenance scheduler on Workers to automatically enforce safety constraints across 330+ data centers, replacing error-prone manual coordination. The scheduler models infrastructure and product relationships as a typed graph, so Workers fetch only the relationships relevant to a maintenance request and avoid memory bloat. A layered fetch pipeline with request deduplication, an LRU in-memory cache, CDN caching and backoff retries reduced response payloads ~100x and drives ~99% cache hits for real-time checks.
