When running a proxy server that needs to stay online 24

relying on just one electrical input invites disaster

A momentary power loss may disconnect users, corrupt sessions, and erode trust

To ensure continuous uptime, building redundant power supplies is not just a best practice—it’s a necessity

Redundancy ensures seamless transition between power sources without service interruption

Implementing this requires thoughtful integration of components, settings, and operational procedures

Begin with enterprise-grade hardware featuring dual PSUs

Many enterprise grade servers come with this feature built in

Each PSU operates in parallel, redistributing load dynamically upon failure

Connect each power supply to a separate power circuit

Use power sourced from separate substations to eliminate common failure points

This prevents a single grid issue or circuit breaker trip from taking down your entire server

Implement a dedicated UPS for each redundant power input

They serve as both battery backups and power conditioners for clean, stable electricity

Select a model rated for the full load of your server with sufficient runtime

Hot-swappable battery trays are essential for zero-downtime maintenance

Deploy independent UPS systems to avoid shared failure modes

It's also important to monitor your power systems

Deploy tools that detect PSU faults, battery degradation, and overcurrent conditions

Ensure escalation paths include off-hours responders to guarantee rapid intervention

Integrate with ticketing systems to auto-create service requests

Confirm infrastructure resilience beyond the server itself

If your proxy server is hosted in a colocation facility, confirm they provide redundant power feeds, backup generators, and climate control

Install an auto-starting diesel or hackmd natural gas generator with transfer switch

Complacency kills redundancy—verify each component functions when needed

Finally, document your entire power redundancy setup

Include wiring diagrams, contact information for your power provider, UPS maintenance schedules, and emergency procedures

Clear documentation reduces mean time to recovery and onboard staff faster

True resilience is measured in recovery, not perfection

Engineering redundancy turns potential disasters into minor incidents

7 promise is fulfilled only through deliberate, layered, tested infrastructure
