How do companies handle IT infrastructure located in factories, branch offices, retail shops, and other sites far from the main data center? I'm interested in the practical problems involved, including technician availability, unreliable power, network outages, temperature and humidity, hardware failures, and physical security. When something breaks and nobody from the IT department is nearby, what tools, processes, and local support arrangements help resolve the issue without requiring a long or expensive trip?

A reliable backup path is important. Besides the normal site-to-site VPN, keep a separate management route available through something like a small backup appliance or cellular router. That way, a failed firewall, VPN configuration, or primary circuit doesn’t completely cut off remote access. Label the switches, cables, and power equipment clearly, and keep current photos and diagrams so someone on site can identify the right hardware.
Some failures can’t be solved remotely, especially when equipment needs a company-specific USB update or a physical replacement. For sites that are several hours away or require a flight, it helps to keep duplicate hardware and recovery procedures available for testing. Companies often use contracted technicians or carefully trained local staff for hands-on work, with standardized equipment selected to reduce the number of things that can go wrong.
It’s usually all of those issues at once. Remote sites may have poor power quality, only one expensive ISP connection, inconsistent HVAC, and weaker physical security than the primary facility. The most useful safeguards are UPS systems, remote monitoring, out-of-band management such as IPMI or iLO, remotely controlled PDUs, and a cellular backup connection. A trained local contact who can check indicator lights, reseat a cable, or power-cycle equipment can save an entire day of travel.
Even with good documentation, a local person still has to be willing and able to touch the equipment. We’ve had supposed power or network failures turn out to be a loose cable or a device that had been switched off.
