Windows 10 In-Place Upgrades? Nope…

With the Creators Update version of Windows now well-sorted and generally available, a number of our clients have asked us to upgrade their existing workstations to Windows 10. We respectfully, but incontestably, refuse. While it may be that an existing workstation could technically be able to be upgraded to Windows 10, in our experience, except in large shops that make use of remote imaging, it is always more expensive to do so than buying new… Read more »

The Case For Carrier-Diverse Redundant Internet

As more and more applications and data move to a Cloud environment, it becomes increasingly important to deploy carrier-diverse redundant Internet in one’s offices, along with a firewall/router that can do automatic failover/failback between the two carrier’s circuits. Challenges We recommend this even for clients who are still hosting on-premises, because if you have just one circuit and your ISP goes down, your customers, suppliers and remote employees can’t reach you, and vica versa.
