When the tunnel linking a branch to head office drops, ERP screens, shared folders and internal telephony stop together. Why site-to-site tunnels fail, which redundancy pattern fits which topology, and the three settings that make a tunnel heal itself.
When a single-line office loses its internet, phones, card payments and every cloud application stop at once. The four components of a dual-WAN failover setup, how to choose a second line that fails independently, and what users actually experience during the switchover.
Two strong candidates compete for the backup-line budget: a second wired circuit or a cellular 4G/5G solution. We compare them on infrastructure independence, CGNAT and static IPs, data quotas and latency — and give a clear recommendation for three typical office profiles.

Choosing between a commercial all-in-one monitor and an open-source metrics stack is less about licence fees and more about who will run the system day to day. A five-dimension comparison with three concrete SME scenarios — and why Grafana is not the thing you compare PRTG against.
