MEET HORA: AI THAT FINDS NETWORK ROOT CAUSE IN UNDER 4 MINUTES
MEET HORA: AI THAT FINDS NETWORK ROOT CAUSE IN UNDER 4 MINUTES Why does it still take 15 to 60 minutes to find the root cause of a network incident? Because most investigations are still done sequentially. Engineers jump between monitoring systems, logs, routing tables, and telemetry, manually correlating data across multiple tools. At ITcare, we […]
WHAT CONFERENCES REALLY MEAN FOR ENGINEERING TEAMS
WHAT CONFERENCES REALLY MEAN FOR ENGINEERING TEAMS Industry conferences are often perceived as marketing events, networking opportunities, or simply scheduled gatherings around new technologies. While those elements certainly exist, their real value for engineering teams runs much deeper. Conferences compress experience. In just a few days, engineers are exposed to architectural patterns, operational lessons, failure […]
JUNIPER TROUBLESHOOTING TRICKS
🧰 JUNIPER TROUBLESHOOTING TRICKS In day to day network operations, some of the most disruptive incidents come from very small components. A link drops because an optic stops responding, an interface refuses to come back, or a transceiver behaves inconsistently. Traditionally, this often ends with a request for a field engineer to reseat the module. […]
SPEED VS STABILITY IN NETWORK OPERATIONS. A FALSE TRADE OFF?
SPEED VS STABILITY IN NETWORK OPERATIONS. A FALSE TRADE OFF? In network operations, time pressure is constant. There are always pending tasks, business requests, customer activations, upgrades, and unexpected issues. At the same time, every change introduced into a live environment carries inherent risk. This creates a familiar dilemma for operational teams. Should speed or […]
THE BIGGEST MISCONCEPTION ABOUT 24/7 NOC SERVICES
THE BIGGEST MISCONCEPTION ABOUT 24/7 NOC SERVICES Downtime is not just a technical problem. It is a financial one. According to widely cited industry research, the cost of IT downtime can reach thousands of dollars per minute depending on the business model and sector. Even short lived incidents can quickly translate into revenue loss, customer […]
WHEN NETWORK RECONVERGENCE LOOKS LIKE FAILURE TO MONITORING
WHEN NETWORK RECONVERGENCE LOOKS LIKE FAILURE TO MONITORING Many networks reconverge exactly the way they are designed to. A link drops, traffic shifts, paths update, and services continue to run. But the monitoring system does not understand that behavior. It sees a short change in state and sends an outage alert anyway. The result is […]
A PRACTICAL PATH TO OUTSOURCING WITHOUT UNNECESSARY RISK
A PRACTICAL PATH TO OUTSOURCING WITHOUT UNNECESSARY RISK For many organizations, outsourcing is no longer viewed as an all or nothing decision. Instead of transferring large operational responsibilities in a single step, teams increasingly prefer a gradual and controlled approach. This shift is driven by a simple concern. Large transitions introduce uncertainty, while smaller changes […]
ROUTING POLICIES ARE NO LONGER ROUTE MAPS
ROUTING POLICIES ARE NO LONGER ROUTE MAPS For a long time, routing policy design across many platforms revolved around a single concept. The route map. It worked, but it was rigid, static, and hard to scale. As networks grew and requirements became more complex, this model quickly showed its limits. Modern service provider and data […]
OBSERVABILITY, TELEMETRY, AND THE REALITY OF gNMI IN MULTI-VENDOR ENVIRONMENTS
OBSERVABILITY, TELEMETRY, AND THE REALITY OF gNMI IN MULTI-VENDOR ENVIRONMENTS While many networks are in freeze mode and changes are on hold, there is finally some space for experimentation, learning, and simply playing around with topics we normally postpone. This time at ITcare we decided to spend it diving deeper into observability using telemetry, and […]
MONITORING IS A CORRELATION PROBLEM, NOT A DASHBOARD PROBLEM
MONITORING IS A CORRELATION PROBLEM, NOT A DASHBOARD PROBLEM Many teams today run five or six monitoring tools at the same time. They use LibreNMS for one part, Nagios for another, Icinga for alerts, PRTG or SolarWinds for graphs, and then a few custom scripts on the side. Each tool does what it is supposed […]
