Users report that an internal application has gone slow, the server dashboards look normal, and the network group says nothing changed on their side. So where between the user and the application does the time actually go? Much of that answer comes from traceroute. The command lists every router a packet crosses on the way to its destination, with a timing figure set against each one. Arguments about ownership then come down to a single device on a single route.

In Under the Hood with Go TLS and eBPF, I left socket tracking as an exercise for later. The example used bpf_get_current_pid_tgid() and explicitly excluded concurrent TLS operations. Capturing plaintext was enough for that post. With rustls, later arrived: I could read the HTTP payload perfectly and still attach it to the wrong TCP connection. That’s a frustratingly convincing failure. The request looks right. The response looks right. The application works.

Learn how immutable backups protect data from deletion, encryption, and ransomware attacks so organizations can recover clean copies. Table of Contents Ransomware attacks are a major threat to modern organizations. Cybercriminals encrypt an organization’s data and demand payments to restore access to it. Modern ransomware also attempts to destroy existing backup files to prevent recovery. Therefore, you must protect backup targets with strong data isolation controls.

NetFlow is a popular network protocol for collecting metadata about traffic flows across your environment so that it can be exported for analysis and monitoring. One of the most common issues that users encounter is NetFlow duplication, which occurs when identical flow records from the same conversation are recorded from different sources. Flow duplication inflates traffic data, undermining capacity planning and making top-talker rankings unreliable.

A request to upgrade a saturated circuit is easy to raise and hard to defend. The interface graph proves the link is full. It says nothing about which application, host or conversation filled it, so the spend gets approved on assumption instead of evidence. The same missing detail turns up everywhere else. Incidents run long because the cause is guessed at, capacity planning rests on estimates, and security questions arrive weeks after the traffic record expired.
