No More RC4 for Kerberos

Published 2026-06-24 by Kevin Feasel

Mike Lynn provides a heads-up:

In July 2026 Microsoft is making a change that may impact your environment. The change being implemented will make your environment more secure by no longer accepting the RC4 algorithm for the Kerberos protocol by default. The problem though is it could cause authentication failures, services to not start, and Kerberos to stop working. Microsoft has been working to implement this change since January 2026, and July 2026 is the final phase.

Introducing pg_hardstorage

Published 2026-06-24 by Kevin Feasel

Hans-Jürgen Schönig announces a new open-source project:

PostgreSQL was once primarily deployed on dedicated servers and virtual machines, and now runs across managed database services, Kubernetes platforms, cloud environments, hybrid infrastructures, and everything in between. Many organizations operate several of these models simultaneously, often while supporting growing data volumes and increasingly demanding recovery requirements. As PostgreSQL deployments have evolved, so have the conversations surrounding backup and recovery.

At CYBERTEC, those conversations have been taking place across customer environments, community discussions, architectural reviews, and operational workshops for many years. The result is pg_hardstorage, a new open-source community project focused on PostgreSQL backup and recovery.

VS Code Extension for Availability Group Read-Only Routing

Published 2026-06-24 by Kevin Feasel

Denny Cherry announces an extension:


Microsoft introduced Read-Only Routing to Always On Availability Groups many versions of SQL Server ago. However, Microsoft never added any sort of UI to SQL Server Management Studio. Years ago, DCAC released a Windows application to manage your Read-Only Routing configuration. We’ve converted our Windows application into a VS Code extension called SQL Always On Read-Only Routing Configuration, which you can download from the website or via VS Code.

Implementing IoT-Style Data in Microsoft Fabric

Published 2026-06-24 by Kevin Feasel

Hristo Hristov takes us through a walkthrough:

Hardware sensors or diverse types of equipment can generate IoT data at a high frequency, e.g., every second. Additionally, IoT data can be messy, semi-structured or just have huge volume and many disparate sources. How to ingest and model IoT data in Microsoft Fabric using the medallion lakehouse architecture?

As I was reading through this, the thing that kept coming to my mind is, if we’re really working with device data at a fairly high periodic frequency (e.g., once a minute or more often), this is probably a job for the Eventhouse and KQL. Though if your devices either don’t collect push information more frequently than, say, hourly, this approach is probably fine.

Thoughts on Deploying Fabric Data Agents

Published 2026-06-24 by Kevin Feasel

Marc Lelijveld performs a deployment:

Over the past year, I’ve frequently blogged about Fabric Data Agents. Alongside myself, many other community members have been sharing their experiences and best practices to get the most out of Data Agents. However, there is one topic I rarely see discussed: deployment of Data Agents.

As Data Agents become part of production-grade solutions, deployment and lifecycle management become increasingly important. Building a Data Agent is one thing, but moving it consistently between Development, Test, and Production environments is a completely different challenge.

In this blog, I will share my current best practices around deploying Fabric Data Agents, including what works today, where the limitations are, and the gaps that still exist.

Read on to see what Marc recommends at this time, with the proviso that some of this will likely change as the product develops further.
