Wildfire evacuation warning: an IT plan for Thousand Oaks offices

Most Thousand Oaks businesses sit close to open hillsides, and anyone who has worked in the Conejo Valley through a Santa Ana wind season knows how quickly a fire can change the day. When an evacuation warning comes in, the people in the office have minutes, not hours, to decide what to take, what to switch off and how the business will keep answering customers. Those minutes go much better if the IT decisions were made in advance.

Know the difference between a warning and an order

California uses two levels of evacuation alert. An Evacuation Warning means there is a potential threat and you should get ready to leave, and leave now if you need extra time. An Evacuation Order means there is an immediate threat and you must go. For an office, the warning is the moment to act on your IT plan. Once an order is issued, nobody should stay behind to unplug a server.

Make sure the right people hear about it. Sign up for VC Alert, Ventura County's emergency notification system, using the office address and the cell numbers of whoever opens and closes the building. Look up the evacuation zone your office is in on the county's official emergency information site, vcemergency.com, and write the zone name in your continuity plan so staff can match it against alerts quickly.

Decide what gets carried out, and keep the list short

People in a hurry grab the wrong things. A short written go-list, taped inside the server closet door and kept in your plan, removes the guesswork. For most small offices it looks something like this:

• Company laptops and their chargers. If staff use desktops, decide in advance whether they will work from a laptop, a home computer or a loaner instead, because towers rarely make it into the car.
• Hardware security keys and MFA devices. If anyone signs in to Microsoft 365, banking or your line-of-business software with a physical key or an office phone, that item must leave with them, or they will be locked out wherever they end up.
• Any local backup drive that rotates off-site. If yours is connected to the server most of the week, it only protects you if someone takes it.
• The emergency contact sheet: your IT provider, internet provider account number, phone provider, landlord and insurer.

Notice what is not on the list: the server, the NAS, the printer, the firewall. Heavy equipment is not worth anyone's safety, and if your data is properly protected elsewhere, losing the hardware is an insurance and logistics problem rather than a business-ending one.

Make sure losing the building does not mean losing the data

The go-list only works if the real copy of your data is not sitting in the office. Before fire season, confirm three things: that every important folder and system is backed up somewhere outside the building, that someone has actually restored a file from that backup recently, and that the people who would need to start a recovery know how to log in to it from a phone or a borrowed laptop. Our backup and disaster recovery page explains how we approach this for offices across Ventura County.

Shut down or leave running?

This is the question offices most often get stuck on during a warning, so decide it now. A reasonable default for most small businesses:

• If you have time and it is safe, shut down any on-site server or NAS cleanly. A fire nearby often means power shutoffs or line damage, and a clean shutdown avoids corrupted files and long RAID rebuilds when the power returns.
• Leave the internet router and firewall running if you rely on remote access to anything in the office, such as a phone system or a security camera recorder. If they lose power, they lose power; nothing is gained by switching them off first.
• Do not stay to finish a backup job. If the last backup is from last night, that is the copy you will work from.

Write the shutdown steps down in plain language, in order, so whoever is last out can follow them without calling anyone.

Keep answering customers from somewhere else

An evacuation can keep a building closed for days, and smoke and closures can shut nearby offices even when the fire never reaches them. Plan for the team to work from home or from a temporary location outside the area:

• Check that every person who needs to work remotely has a company laptop, can sign in with MFA away from the office, and can reach shared files or the business application they depend on.
• If you use cloud phones, set up call forwarding or a mobile app in advance so the main number rings somewhere useful. If you use a traditional phone line, ask your provider now how to redirect it remotely.
• Have a short message ready for your website, email auto-reply and voicemail that tells customers you are open and how to reach you.

Our remote and hybrid work support covers getting staff set up so a sudden move away from the office is a minor change rather than a scramble.

Coming back: smoke, ash and a careful restart

Only return when the authorities lift the order and the building is confirmed safe. Even when an office escapes the flames, smoke and fine ash can get into computers and network equipment, and ash is corrosive when it mixes with moisture. Before powering anything back on:

• Look for ash or soot on and inside equipment, especially anything with fans and vents. Do not blow it around with compressed air indoors; have it cleaned properly or assessed first.
• Check for water damage from firefighting or sprinklers. Anything that got wet should stay off until it has been checked, because powering on a wet drive or server can turn a recoverable situation into a lost one.
• Bring systems up in order: power and UPS, then the internet connection and firewall, then switches and Wi-Fi, then servers and storage, then desktops. Confirm backups are running again before the team gets back to normal.

If a server or drive will not start, or was exposed to heat, smoke or water, stop and get help rather than trying repeated restarts.

Put it in your continuity plan before the next red flag day

All of this fits on two pages: the alert sign-ups and evacuation zone, the go-list, the shutdown steps, the remote-work and phone setup, and the restart order. Review it each fall before the strongest wind events, and walk new staff through it. If you would like help writing or testing that plan, our business continuity work and IT support for Thousand Oaks businesses are a good place to start.
