Central Pacific hurricane season runs from June through November, and the part that affects most Hawaii businesses is not a direct hit. It is power. A tropical system a long way offshore, a line down in the wrong place, a substation issue on a hot afternoon, and a few hundred businesses lose an afternoon each.
After enough of these, a pattern shows up. The expensive equipment is almost never what fails. What fails is the cheap thing nobody tested.
The battery is the thing
Nearly every office has a UPS, the box under the rack that is supposed to hold the systems up long enough to shut them down properly. In our experience it is the single most common point of failure during an outage, for a simple reason: its batteries wear out in roughly three to five years, it does not tell anybody, and nobody tests it.
We have been called to an outage, arrived the following morning, and found the UPS entirely dead, not low, dead. Everything downstream had simply dropped. The storm did not break it. It had been broken for a while and the storm was the first thing to ask.
A UPS that beeps is not a UPS that works. The only real test is a load test: pull the mains and see what actually stays up, and for how long. Do that on a quiet Tuesday, not during a warning.
While you are there, look at what is plugged into it. Racks accumulate. It is very common to find the server on battery and the switch it talks to on a wall socket, which means when the power goes, the server survives and nothing can reach it. Check the firewall, the switch, and the modem or ONT too. A protected server behind unprotected networking is a protected server nobody can use.
What else actually goes
- Internet, after the power comes back. Equipment powers up in the wrong order, the modem comes up before the fibre is stable, and the network sits there unhappy until someone power-cycles things in sequence. Know your order, and write it down.
- The door and alarm systems. Access control and alarm panels have their own small batteries with their own quiet expiry dates. Being unable to open your own office is a bad way to find out.
- Anything that needs a person. If the fix is physical and your IT is remote, the outage lasts until someone can be there. That is worth knowing in advance rather than discovering at 6:00pm on a Friday.
- The backup nobody restored. Backups fail quietly for months. A backup you have never restored from is a belief, not a backup.
The half-day checklist
None of this requires a project. It is an afternoon, and most of it you can do yourself.
Power
- Load-test every UPS. Note how long it actually held, not what the label claims.
- Replace any battery older than about four years, or that failed the test.
- Confirm the network gear, firewall, switch, modem, is on battery, not just the server.
- If there is a generator: run it under load, and check the fuel is fresh and the transfer works.
Data
- Restore something. An actual file, from an actual backup, to an actual machine. This week.
- Confirm at least one copy is off site, not the drive sitting on the shelf beside the server.
- Check that cloud data is backed up too. Microsoft 365 and Google Workspace keep your data available; that is not the same as keeping it recoverable after a deletion.
People
- Print the contact list. Phone numbers for IT, the landlord, the electrician, the internet provider, the alarm company. On paper, because the intranet is down in this scenario.
- Decide who declares an outage and who tells staff, so nobody waits to be told twice.
- Make sure two people know the shutdown order, not one.
- Confirm the office phones can be forwarded from somewhere other than the office.
The room
- Nothing on the floor. Water finds the floor first.
- Know which breaker panel feeds the rack, and who controls it. You or the building.
- Write down the building's own emergency contact and their after-hours number.
What we would not bother with
Elaborate written disaster recovery plans that nobody has read. A binder is not preparedness. Two tested batteries, one restored file and a printed phone list beat forty pages every time.
Nor would we move a business to the cloud to solve a power problem. Cloud helps with some of this and does nothing for the rest, your staff still need power and internet in the building to reach it. Solve the power problem as a power problem.
The one thing, if you only do one thing: load-test the UPS and replace the batteries that fail. It is the cheapest item on this page and the one most likely to be the difference between a quiet afternoon and a lost day.
Want someone to walk the room with you?
We will test the batteries, check what is actually protected, confirm your backups restore, and leave you a one-page record of your own building. Thirty minutes, no obligation.
