Modern Firewall Architecture Moves Beyond the Network Edge
📅 - A firewall used to have an obvious address in the network: somewhere between the company and the Internet. That model is increasingly inadequate for hosting providers, cloud operators and enterprises running distributed infrastructure. Traffic now moves between applications, racks, data centers, clouds and management systems, making firewall placement, policy ownership and internal segmentation as important as whatever happens at the external perimeter.
The basic function has not changed much. A firewall observes network traffic and decides whether to permit or block it according to policy. What has changed is the network around it.
A server may accept connections from customers, [...][... Check source for end of article ...]
📅 - Lenovo Server Business Surges on Cloud and AI Infrastructure - Lenovo's infrastructure business nearly doubled quarterly revenue as demand from cloud providers and enterprises drove server sales sharply higher, giving the Chinese technology group a larger role in an AI infrastructure market still constrained by power, accelerators and capital. The company reported $8.5 billion in infrastructure revenue for its fiscal first quarter, up 98% from last year.
For cloud operators and data center buyers, the more interesting number sits elsewhere in Lenovo's results. Its AI server pipeline has reached $54 billion, an increase of 157% from the previous quarter. Pipeline is not revenue, and Lenovo does not disclose how much of that figure represents firm [...]
📅 - Eaton Wins $7M US Air Force Contract for Quantum Grid Threat Research - Eaton has secured a $7 million, 24 month U.S. Air Force Research Laboratory contract to test whether quantum computing, machine learning and visualization can help grid operators identify and respond to simultaneous physical and cyber threats. Working with Infleqtion and Penn State, Eaton will develop hybrid quantum classical methods aimed at a difficult power system contingency problem.
The research targets a computational problem that becomes substantially harder as the number of possible failures increases. North American Electric Reliability Corporation requirements currently call for transmission systems to withstand two sequential failures, described as N-2. Eaton's AFRL-funded work [...]
📅 - JLL: North American Data Center Demand Hits 25 GW as Vacancy Stays at 1% - North American data center demand hit 25 GW in the first half of 2026, according to JLL, doubling year over year even as vacancy stayed near 1%. The boom is pulling capital, power and construction into markets, but the constraint is shifting. Capacity can be financed. Community approval, grid access and tolerance may prove harder to secure.
The numbers are large enough to change how infrastructure buyers should read the market. JLL says 66 GW is under construction across North America and 95% of that capacity is already committed. Tenants signing today are often buying delivery years out, including for 2028. That is not a normal procurement cycle for many enterprise IT teams, which still [...]
📅 - Nebius Takes Vantage Colocation Capacity for UK AI Infrastructure Build - Vantage Data Centers and Nebius have agreed to deploy high-density NVIDIA-based AI infrastructure at Vantage's CWL1 campus in Newport, creating the first announced commercial capacity commitment in South Wales' AI Growth Zone. The deal gives Nebius another UK foothold while tying government ambitions for domestic compute more directly to available power, cooling, connectivity and data center capacity.
Nebius will lease capacity rather than build the Newport facility itself, using CWL1 for AI training, inference, agentic applications and enterprise workloads. The customers being targeted range from startups and researchers to enterprises and public-sector organizations. Neither company [...]
📅 - Namecheap, Hosting.com Hit by Phoenix Data Center Outage - A prolonged cooling failure at RadiusDC's Phoenix data center has knocked services offline for multiple hosting providers, including Namecheap and Hosting.com, exposing how a single facility problem can cascade across websites, email, DNS management and customer support. Recovery efforts were still underway Thursday, with temperatures falling only after chillers and temporary cooling equipment were brought back online.
The August 13 incident originated at the Phoenix facility where phoenixNAP operates as a tenant. PhoenixNAP's status system said elevated temperatures followed multiple utility disturbances linked to overnight storms. RadiusDC, identified by phoenixNAP as the facility [...]
📅 - Data Center Boom Forces Insurers to Rethink Infrastructure Risk - Artificial intelligence is turning data centers into one of the world's largest infrastructure investment classes, while insurers are discovering that the risk no longer resembles ordinary commercial property. Annual spending could exceed $1 trillion by 2027, as bigger campuses, denser computing equipment and concentrated dependencies raise potential losses from fire, weather, power failures and prolonged outages for customers.
The numbers are becoming difficult for insurers, lenders and infrastructure investors to treat as another real estate cycle. Data center investment is projected to rise from roughly $500 billion in 2024 to more than $1 trillion as early as 2027. The United States [...]
