First of all networks don't 'crash'. Second, you can't answer the question until you know what caused the impact. Then you make a plan to prevent the scenario from happening again

First, check the budget and network requirement, then make all hardware on specification, if using wlan check channel is it overlap? Qos setting/limit per user, and choose good ISP

The first thing to do is to fix it, get involved in the process, understand the problem and its solution. Then we can determine the preventive measures, whether it is upgrading hardware software, load or traffic balancing, rerouting, optimization or maybe its just a simple connector problem

Regular Maintenance like checking hardware and firmware updates also Capacity Planning to so that you can support increased traffic in future can help reducing such incidents

To prevent network crashes during peak hours, implement capacity planning to handle high traffic, upgrade infrastructure, and use scalable cloud solutions. Employ load balancers to evenly distribute traffic and establish redundancy with failover systems. Implement QoS to prioritize critical services and deploy real-time monitoring tools to identify bottlenecks early. Utilize caching and CDNs to reduce server load and conduct regular stress tests to find vulnerabilities. Keep hardware and software updated and optimize configurations. Communicate proactively with users about maintenance and outages to maintain trust and reliability.

I would carefully monitor traffic patterns and use load balancing to appropriately spread data flow. Upgrades to network infrastructure, such as failover systems and greater bandwidth capacity, will enable continuous operation even under high demands. Non-essential traffic congestion can be prevented by prioritising vital applications and enforcing Quality of Service (QoS) requirements. Proactive monitoring, including automatic alerts and periodic stress testing, would help to discover and resolve such issues before they cause disruptions. Furthermore, obtaining dedicated bandwidth through configuration optimisation and partnership with ISPs would increase network reliability during peak demand periods.

Diagnose the Root Cause Analyse logs to identify failure points (bandwidth overload, hardware failure, software bugs) Use network monitoring tools to track real-time performance and pinpoint issues. Conduct stress testing to simulate peak-hour conditions.

Ensuring network stability during peak hours is crucial for seamless operations. In addition to upgrading infrastructure, implementing load balancing, and continuous monitoring.

Identify the root cause, check for recurrence, and implement preventive measures based on historical data (e.g., power issues, transport capacity, transmission failures).
