E-learning course: Diagnosing a critical network outage
Estimated duration: 1.5 hours – Level: Advanced – 100% online format
Your networks can’t go down. Neither can your skills.
A critical network outage doesn’t wait. Every second of inaccessibility costs money. This expert course trains senior network support technicians to react quickly and effectively to a major incident. You will learn to diagnose methodically, identify root causes, communicate effectively in a crisis situation, and activate transitional solutions until service is fully restored.
➡️ Through 6 progressive and operational modules, you will strengthen your technical and decision-making skills:
1. Why every network second counts
Put into perspective the business and security challenges of a critical network outage. Discover the real impacts of an interruption – financial, operational, human – and measure the strategic responsibility of your role during these emergency situations.
2. The fundamentals of network diagnosis
Master the basic principles of network operation, from reference models (OSI, TCP/IP) to routing mechanisms, DNS, DHCP, firewalls, to better structure your checks.
3. Best diagnostic practices
Develop a step-by-step approach: symptom identification, multi-layer analysis, identification of breaking points, connectivity tests, log decoding, etc. Learn to think “probable cause” but always verify.
4. Adapt your method to the crisis context
Create responses adapted to different contexts: incidents on a central switch, VPN failure, Internet outage, bandwidth saturation. Adjust your priorities according to the environment, the level of urgency, and the impacted user profile.
5. Immersive Simulator: The High-Voltage Call
Put yourself in the shoes of an on-call technician called for a sudden network outage. Faced with a virtual character, practice questioning, prioritization, technical escalation, and relational de-escalation.
6. Final Mega Quiz
71 progressive questions, scripted and personalized based on your previous answers. Ideal for memorizing, anchoring, and testing yourself right up to the last second.
Who is this training for?
This course is designed for experienced network support technicians who work daily in high-stakes contexts (critical structures, sensitive information systems, multi-site infrastructures).
No more suffering from outages. Anticipate, act, control.
