IANA says the DNS root zone began using KSK-2024 on October 11, 2026. DNSSEC-validating resolvers must trust key tag 38696 to avoid validation failures.
-
Marvell is bringing 102.4T Ethernet switching, CXL memory expansion, 1.6T optics, PCIe 6.0 storage and hardware security to OCP Global Summit 2026 as AI infrastructure bottlenecks move beyond GPUs.
-
XMax agreed to acquire Hexa Creation for about $4.12 million, adding a 1200V vertical-GaN power semiconductor roadmap aimed partly at emerging 800VDC AI data-center power systems.
-
Every NFL game runs on a technology stack that looks increasingly like a mobile data center: RFID player tracking, ultra-wideband receivers, AWS machine learning, Sony Hawk-Eye replay and measurement, private wireless coach communications, and thousands of hardened Surface Copilot+ PCs.
-
Learn ROADM and optical line-system engineering: WSS operation, ROADM degrees, colorless/directionless/contentionless/flex-grid architectures, amplification, power equalization, OCM, OSNR, C+L scaling, restoration, open line systems, commissioning, and troubleshooting.
-
Formula 1 has reduced its trackside Event Technical Centre from three racks of IT equipment to one while moving more telemetry processing back to the circuit. Lenovo says the new setup processes about 8 TB of telemetry per race weekend and can cut delivery latency to teams by up to 0.3 seconds.
-
Learn a disciplined fiber troubleshooting and restoration workflow: inspect and clean, verify power and polarity, isolate with VFL and OTDR, identify bends and breaks, restore service, retest, and document the repaired link.
-
An HMI is the operator interface used to see and control a machine or process. SCADA is the larger supervisory system that can connect many PLCs, RTUs, HMIs, alarms, historians, servers, and remote sites. They overlap, but they are not the same thing.
-
NVIDIA’s Seattle Robotics Lab has built robotic systems that can assemble parts of GB300 tester trays, including busbars and high-density connectors. The results are promising but still short of the manufacturer’s deployment targets.
-
Learn data center network fabric engineering: Clos and leaf-spine topology, ECMP, BGP underlays, oversubscription, redundancy, EVPN-VXLAN overlays, failure domains, and validation.
-
A PLC and a PAC can look almost identical, but they were built around different levels of automation complexity. PLCs excel at focused machine control; PACs extend that model into larger, multi-domain systems with more data, networking, motion, and process control.
-
Learn server network configuration and validation in the data center: NIC discovery, link state, optics and DACs, VLANs, bonding/LACP, LLDP, ethtool, nmcli, MTU checks, packet counters, troubleshooting, and handoff validation.
