This article explains how recent router compromises, highlighted by national security advisories, are typically the result of outdated software and misconfiguration rather than vendor-specific flaws. It outlines how proper firmware management, firewall design, and lifecycle awareness significantly reduce risk. It also emphasizes the role of proactive support, such as services from LinkTechs, in maintaining secure and reliable network infrastructure.
Email authentication is no longer optional—Google and Yahoo now enforce strict SPF, DKIM, and DMARC requirements, and domains that are not properly configured are increasingly seeing emails flagged, delayed, or rejected outright. Many businesses assume their email is working when in reality they are losing deliverability and exposing themselves to spoofing risks. Link Technologies, Inc. can audit and validate your domain’s SPF and DMARC configuration, identify gaps, and ensure your email systems are secure and compliant. By addressing these issues now, you can prevent communication failures, protect your brand, and avoid future disruptions—contact us at sales@linktechs.net or 314-735-0270, submit a ticket at https://hd.linktechs.net , or review our services at https://shop.linktechs.net/what-we-do and https://shop.linktechs.net/support-services .
The FCC’s new restrictions on foreign-made consumer routers are expected to impact future hardware availability, especially for widely used MikroTik edge devices. While existing equipment remains unaffected, supply constraints and price increases are likely as new models face approval challenges. Now is the time to secure MikroTik inventory to avoid delays and keep your deployments moving without interruption.
Link Technologies, Inc. specializes in high-availability network design and engineering for ISPs and WISPs, delivering robust, carrier-grade architectures that dramatically improve uptime, performance, and operational efficiency while lowering recurring costs. Their team engineered a centralized data center architecture with redundant routing, firewall, and monitoring systems that eliminate cloud dependency, accelerate DNS performance with aggressive local caching, and ensure automatic failover across POP sites—giving operators full control and resilience in the face of network challenges.

Owning and operating your own DNS infrastructure is essential for ISPs who want full control over performance, reliability, and customer experience instead of outsourcing a critical service to public resolvers like Cloudflare or Google. By deploying local, recursive DNS servers with robust caching and security policies, you eliminate blind spots during outages, accelerate lookups for end users, and empower your support teams with real-time visibility and troubleshooting capabilities.

Navigating the FCC Broadband Data Collection (BDC) process starts with obtaining access to the Broadband Serviceable Location Fabric—the foundation of the FCC's broadband mapping initiative. In this guide, we explain who can access the Fabric, how the licensing and approval process works, and what ISPs and WISPs need to know to streamline BDC submissions, Fabric challenges, and broadband planning. Learn how TowerCoverage.com and Link Technologies can simplify the entire FCC reporting process with integrated mapping, engineering, and File On Behalf Of (FOBO) services.
Dennis Burgess, CTO of Link Technologies, emphasizes that effective network monitoring is foundational to ISP reliability and customer experience. He recommends deploying at least three core systems—a high-level overview tool (like The Dude), a deep monitoring platform (such as Zabbix), and external internet monitoring—to ensure visibility, rapid troubleshooting, and proactive alerting. A fourth system, BGP monitoring, becomes critical for networks with multiple upstreams to detect routing issues that may not trigger session failures. Together, these layered monitoring approaches improve uptime, reduce support load, and ensure a resilient, well-managed network.
