Possible challenges before choosing this path.
Network operations roles may require night shifts, weekend support, maintenance windows, and urgent outage response.
Network outages can affect many users, business systems, customers, and revenue, creating pressure during troubleshooting.
Networking changes with cloud, SD-WAN, zero-trust, automation, IPv6, Wi-Fi standards, and security tools.
Basic monitoring and routine configuration tasks may be automated by orchestration, AI operations, and network management platforms.
Poor diagrams, IP records, change logs, and configuration backups can increase outage duration and operational risk.
Work may depend on ISP response, hardware vendor support, licensing, warranty status, and third-party escalation timelines.
