Hurricane Preparedness for Business IT: Florida Checklist

Q: Should I turn off my business server before a hurricane?

Yes. Shut servers, storage and network equipment down cleanly before the power fails, then unplug them from the wall. This avoids corrupted data from a sudden outage and protects against the voltage surge that often accompanies power restoration. Restart in order after the storm: UPS, modem and firewall, switches, servers, then workstations, once you have confirmed stable power and no water intrusion.

Q: How can my business phones keep working during a hurricane?

A cloud-based VoIP system can forward your main number to cell phones, play a storm greeting and route calls to staff who have evacuated, because the phone service lives in a data center rather than in your office. Configure and test the failover rules before the season starts. Traditional lines that depend on local wiring and office power cannot offer this.

Q: What IT preparation should be done 72 hours before a hurricane?

Confirm backups completed and trigger an extra offsite copy, send staff home with laptops and verify they can log in remotely, set the storm greeting and call forwarding on the phone system, shut equipment down cleanly and unplug it, cover racks against leaks, and raise anything sitting on the floor. Keep a printed contact and vendor sheet with you.

Hurricane preparedness for business IT comes down to five things you should finish before June: verified offsite backups, protected and cleanly shut-down equipment, a way for staff to work from anywhere, phones that ring even when the office is dark, and a written restart sequence for after the storm. Do those five and a hurricane becomes an inconvenience rather than a business-ending event.

We have supported Treasure Coast businesses through enough named storms to know that the damage is rarely the wind. It is the week of power flickers, the surge when the grid comes back, the humidity in a sealed office, and the scramble to reach staff who evacuated. This checklist is what we walk through with clients in Vero Beach, Sebastian, Fort Pierce, Port St. Lucie and Stuart each spring.

Before the season: what should be done by June 1?

1. Verify backups are offsite and restorable

Confirm every server, workstation with local data, and your Microsoft 365 tenant is backed up to a location outside the county, not just a drive in the server closet.
Run a real test restore of a file, a mailbox and, if you have a server, a full server boot. Record the date and how long it took.
Check retention: if the storm hits during the last week of the month, will you still have last month's payroll files?

Our backup and disaster recovery service includes scheduled test restores because we have seen too many backups that ran every night and restored nothing.

2. Protect power and equipment

Put every server, switch, firewall and phone appliance on a battery backup (UPS) with enough runtime for a clean shutdown, and replace batteries older than three years; Florida heat shortens their life.
Use surge protection at the panel and at the rack. The restoration surge after an outage kills more equipment than the outage itself.
Move servers and network gear off the floor and away from exterior walls and windows.
Photograph serial numbers and keep a current equipment inventory for insurance claims.

3. Make remote work possible for everyone who matters

Identify which roles must keep working (billing, dispatch, patient scheduling, client communication) and confirm each has a laptop, a charger, MFA set up and a tested way to reach files and applications from home.
Move files still living only on a local server to SharePoint, OneDrive or a hosted environment where practical.
Test that remote access works from a phone hotspot, because home internet is often the first thing to go.

4. Set up phone failover

A VoIP system can forward the main number to cell phones, play a storm message, and route calls to staff who evacuated to Orlando. A legacy phone line on a wet pole cannot. Configure the failover rules now and test them; our business phone systems page explains how this works.

5. Build the contact and vendor sheet

Staff cell numbers and personal emails, printed and stored in the cloud.
Internet provider, power company, landlord, insurance agent, IT provider, software vendors and payment processor, with account numbers.
Administrative passwords in a password manager with an emergency access process.

When a storm is 72 hours out: what should you do?

Confirm last night's backup completed and trigger an extra offsite copy.
Send staff home with laptops and chargers; verify each can log in remotely before they leave.
Post the storm greeting on the phone system and set up call forwarding.
Shut servers and network equipment down cleanly before the power fails, not during the outage. Unplug from the wall after shutdown to avoid restoration surges.
Cover racks and equipment with plastic sheeting in case of roof or window leaks.
Raise anything on the floor: printers, UPS units, boxes of paper records.

What is the safe restart sequence after the storm?

The most avoidable damage we see happens when someone flips everything on the moment power returns. Follow this order:

Inspect first. Check for water intrusion, humidity condensation on cold equipment and damage to cabling. Let equipment sit in air conditioning for a few hours if the building was sealed and hot.
Confirm stable power. Wait for the grid to hold for a while before reconnecting; restoration often includes several more outages.
Power on in order: UPS, then modem and firewall, then switches and Wi-Fi, then servers and storage, then workstations and phones. Give each layer a few minutes.
Verify internet and remote access before calling staff back.
Check backups ran and email flows before declaring the office open.
Watch for phishing. Scammers send fake insurance, FEMA and vendor messages within days of a landfall. Remind staff.

What if the office is unusable?

If the building is flooded or without power for weeks, the businesses that recover fastest are the ones whose critical systems already live in the cloud or can be booted from a cloud copy. This is where disaster recovery planning pays off: a documented process for standing up your server elsewhere, redirecting phones and getting staff productive from home or a temporary office. If you have not planned this, a conversation with our cloud and hosting team before the season is worth an hour of your time.

The simple self-audit

Can I restore my most important system today, and how long would it take?
Would my key staff know how to work from home tomorrow?
Will my main phone number ring somewhere if the office is dark?
Do I have a printed contact sheet and the login credentials to run the business without my IT closet?
Have I written down the restart sequence so anyone can follow it?

If any answer is no, we can help you fix it before the first named storm. MainSail Data offers a free hurricane readiness assessment for Treasure Coast businesses. Call (772) 794-1194 or contact us online and we will walk through your office together.
