Border Gateway Protocol (BGP) remains the backbone of inter-domain routing on the Internet, but its fundamental trust model leaves it vulnerable to misconfigurations, hijacks, and blackholing. When these issues occur, they often go undetected by the impacted networks—until users report degraded performance or service outages. This post walks through a real-world incident in which a legitimate traffic spike led to an upstream provider mistakenly blackholing a critical IP address.

When an alert fires, your goal is clear: fix the problem—fast. But traditional troubleshooting rarely makes that easy. You’re immediately thrown into decision mode: All the while, the clock is ticking. The longer you’re stuck guessing what to do next, the longer your downtime drags on, and the more non-value-added engineering time you burn.

As your organization scales its Datadog footprint, you want to understand what’s driving cost changes and promote cost awareness. But to take meaningful action, you need more than a monthly bill—you need real-time, contextualized cost data tied to services and teams. Without this visibility, it’s hard to assign ownership, prevent cost overruns, or identify which changes are affecting spend.

Debugging modern.NET apps isn’t as simple as scanning logs anymore. With services spread out and systems growing more complex, it's easy to miss the bigger picture. Serilog gives you clean, structured logs. OpenTelemetry brings in traces and metrics to connect the dots. This guide covers how to wire up Serilog with OpenTelemetry, send logs to traces, and build an observability setup that helps you troubleshoot, without digging through disconnected logs for hours.

Logs are essential, but managing them can be tedious. They quickly consume storage, slow down your searches, and make troubleshooting feel like an endless chore. Loki monitoring helps simplify this process, offering a more efficient approach to logging that developers can appreciate.

Amazon Inspector is an automated security assessment service that scans AWS workloads for vulnerabilities, misconfigurations, unintended network exposure and compliance risks, helping organizations enhance cloud security, detect threats, and meet regulatory requirements (such as ISO/IEC 27001, HIPAA, NIS 2 and SOC 2 Type 2) in real time. Amazon Inspector discovers and scans Amazon EC2 instances, container images in Amazon ECR (Elastic Container Registry), and Lambda functions.

In the dynamic world of IT operations, a common misconception has emerged: Observability vs Monitoring is often framed as a battle where one replaces the other. At Icinga, where open-source monitoring is our expertise, we aim to clarify this misunderstanding. Observability doesn’t supplant monitoring—it complements and enhances it. The term “Observability” has become a buzzword in the tech industry, often touted as the modern solution to outdated, static monitoring practices.

With the introduction of cloud services and microservices, applications have become more complicated due to their increased layers of complexity and distributed architecture. While microservices clearly offer speed, they also make things harder for the developers and operations teams. These teams need to plan for the reliable and efficient performance of such applications. To combat these challenges, application performance monitoring (APM) has surfaced as an indispensable discipline.

Change is constant, but without a structured approach, it can lead to confusion, resistance, and costly disruptions. A well-planned change management process ensures transitions happen smoothly, minimizing risks while keeping teams aligned and operations running efficiently. Whether adopting new technology, restructuring teams, or refining business strategies, organizations that manage change effectively turn challenges into opportunities for growth.
