Canonical and Ubuntu RISC-V: a 2025 retro and looking forward to 2026

2025 was the year that RISC-V readiness gave way to RISC-V adoption. It’s been quite a journey. What began years ago as early architectural exploration and enablement has matured into real silicon, systems, and deployments. In particular, RVA23 provides a stable and predictable baseline we can align on with our wider ecosystem of partners. At Canonical, we’re committed to making RISC-V a viable option for anyone who wishes to adopt it.

Understanding L1, L2, L3 escalation policy

L1, L2, L3 is one of the most common ways to structure an escalation policy. The idea is simple: an incident triggers and lands with a first responder. If it needs more attention, it moves up the chain to someone with more expertise. This guide explains how each tier works, when this structure makes sense, and what to keep in mind when setting one up.

The Complexity Myth in Test Data Management

This is a guest post from James Hemson. For years, the test data management market has told smaller companies the same story. Test data is complex. You need consultants. Compliance is expensive. Expect a six-month implementation before you see any value. At Redgate we think that's wrong. And we think it's wrong by design. Complexity creates services revenue. It creates switching costs. Most vendors have built their businesses around this.

Grafana Campfire - Back to Basics - (Grafana Community Call - Feb 2026)

Grafana Campfire Community Calls are back. We are starting with *Back to the Basics.* Even though you heard it so many times, but some of you are either new to or not very experienced with terms such as monitoring, observability, metrics, tracing, profiling etc. The good news is that you're not alone, and we've got this!! This will be a perfect learning opportunity to gain understanding during this live call and ask questions if anything is not clear.

Block Builder: a new Mimir Component (Mimir Community Call February 2026)

At today’s community call, we will hear from David Grant, one of the engineers who has brought a new component, the Block Builder, into Mimir. Using the Ingest Storage architecture in Mimir 3.0, the Block Builder takes over the block-building responsibility from the Ingester. This feature is experimental in Mimir today, but is rolling out to production inside of Grafana Labs now. This is a great time to introduce the component, discuss the motivation, and show where it fits in the larger architecture.

Escalation policies for critical incidents

When a critical incident triggers, there’s no time to figure out who to call. That decision needs to be made well before the incident arrives. A dedicated escalation policy for critical incidents gives your team a clear path to follow the moment things go wrong, rather than leaving it to whoever happens to be around. This guide covers the key decisions involved in building that policy.
