You probably should avoid ctx.WithTimeout or ctx.WithDeadline with code that makes network calls. Here is why.

DNS Check's load balancer monitoring now supports CIDR notation, making it practical to monitor domains served by CDNs and cloud providers that use large IP pools. Instead of listing every possible IP address a provider might return, you can enter CIDR ranges like 104.16.0.0/13 and DNS Check will verify that responses fall within those ranges.

Windows Firewall is enabled by default, right? How sure are you? Even if you are 99.999% sure, this is how you have a possible vulnerability on your hands. There are numerous cases where someone disables Windows Firewall temporarily to troubleshoot a connectivity issue. The problem gets resolved. The firewall stays disabled—for months. Nobody notices until the security team investigates why sensitive data is suddenly appearing on dark web marketplaces.

This report analyzes cloud provider status data for January 2026, covering 12 major cloud platforms: AWS, Azure DevOps, DigitalOcean, Fly.io, Heroku, Linode, Microsoft Azure, Netlify, Railway, Render, and Vercel. The data includes official incident reports from each provider's status page and early detection capabilities from IsDown's monitoring system.

Percepio TraceExporter for VS Code makes it easy to export Percepio TraceRecorder snapshots during your debug session and open them directly in Percepio Tracealyzer. This is applicable for embedded systems based on Zephyr, FreeRTOS, SafeRTOS, Cesium, ThreadX or PX5, or using TraceRecorder’s “Bare Metal” option. The extension is currently provided in a Beta version as a downloadable.vsix file.

When your company’s help desk receives fifteen "my connection is slow" tickets from remote employees in a single morning. Your network monitoring dashboard shows everything green; VPN concentrators running smoothly, bandwidth usage normal, no alerts. Yet employees can't get their work done. You try to ping their home routers. Nothing. Attempt a traceroute to diagnose the path. It dies at the ISP edge. Check your SNMP queries. They never make it past the residential gateway.

Google SecOps (formerly Chronicle) is widely used for large-scale security analytics, long-term telemetry retention, and detection across diverse environments. Its Unified Data Model (UDM) enables correlation across sources and supports analytics that operate over long time horizons. To take full advantage of these capabilities, security data must arrive in a consistent and well-structured UDM format. In practice, this is rarely the case.

A repository for this article can be found here.‍ When most developers think about request tracing, they picture instrumentation hooks inside familiar libraries. This allows us to track familiar metrics we see in application performance monitoring (APM) tools such as the duration of an HTTP call or how long a database query takes. But what if you could go deeper and instrument your own Ruby code automatically, without sprinkling timing calls everywhere?
