YouTube Outage (Feb 17, 2026). What Happened?
On February 17, 2026, YouTube went down for users worldwide.

SREs and application developers rely on telemetry data to understand and improve their systems. As organizations scale and evolve, those systems generate an ever-growing volume of metrics, logs, and traces. But more data alone does not make it easier to improve performance or reliability: Identifying meaningful optimizations still requires careful investigation and analysis.

Understanding Namespaces in Icinga 2 DSL

Designing Alerts for Action
In the first two posts of this series, we explored how alert noise emerges from design decisions, and why notification lists fail to create accountability when responsibility is unclear. There’s a deeper issue underneath both of those problems. Many alerting systems are designed without being clear about the outcome they’re meant to produce. When teams don’t explicitly decide what they want to happen as a result of a signal, they default to the loudest option available.
