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.
RouterOS Apps introduce a simplified way to deploy containerized services directly on MikroTik routers, allowing operators to run infrastructure tools such as DNS, monitoring, and logging without separate servers or virtualization platforms. With just a few clicks, RouterOS automatically deploys containers along with required networking and firewall configuration. This capability enables ISPs and network operators to host operational services closer to the network while reducing complexity and infrastructure overhead.
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.
