Business Continuity Planning: How to Prepare for Internet, Power, and Vendor Outages

Picture a Tuesday morning in Mississauga: the internet is down, the phones are dead, and your order system lives in the cloud. What do people do for the next three hours?

That's the question continuity planning answers. Backups matter, but they won't bring back your internet connection, run a workstation without power, or make a cloud vendor pick up the phone. Continuity planning gets people working safely through the interruption and back to normal in a sensible order.

Find the Work You Can't Easily Pause

List the workflows that need an outage plan. For most offices that's some mix of:

• Customer calls and email
• Order entry and scheduling
• Payments and banking
• Shipping, labels, and inventory
• Remote access and field work
• Payroll and time tracking
• Door access and security systems

For each one, write down the people, applications, internet connections, power, devices, data, and vendors it depends on. That list is the real map of your risk.

Internet Outage

Decide what happens when the main office connection goes down. Look at a second circuit or cellular failover, and which users and applications get priority on the backup. Check that phones, VPNs, and cloud applications work over it. Spell out how staff learn to move or work from home, and how to reach the provider without using the office internet. Plan to test both the failover and the switch back.

A backup connection only counts if it's monitored and has been used. A line that nobody can switch to when it matters is a line item on the invoice.

Power Outage

A UPS buys you time for an orderly shutdown or keeps a few devices up briefly. It isn't a power strategy by itself. Write down:

• Which network, server, phone, and security gear is on battery
• The order you'll shut things down in, and who decides
• What to do in an extended outage
• Who is responsible for the generator, if there is one
• What depends on the building: door access, lighting, cooling, alarms
• How you'll check equipment before it starts back up

Don't switch everything back on at once. Startup order and equipment health matter, especially for servers and storage.

Critical Vendor Outage

Your cloud, telecom, payroll, line-of-business, or payment vendor can fail while everything in your office is fine. For each one, keep:

• Support and escalation contacts
• Contract and account numbers
• Where to find service status and how they communicate
• Data export or offline-work options
• Manual procedures and what they can't do
• Upstream and downstream integrations
• An approved alternative, where one is practical

Be careful with workarounds. A quick fix that creates duplicate records, loosens access controls, or puts customer data in an unapproved place can cost more than the outage did.

Define Operating Modes

Give staff a few simple stages they can remember:

1. Normal: everything is available.
2. Degraded: service is limited, and priority work carries on.
3. Manual: an approved offline or alternate process is in use.
4. Suspended: unsafe or unreliable activities stop.
5. Recovery: systems come back in a controlled order.

Say who can move the business from one mode to the next, and how staff will hear about it.

Communications That Don't Share the Failure

Keep an offline copy of key contacts and pick a backup channel, such as a group text or a messaging app on personal phones. The list should include staff, building management, IT support, your internet and telecom providers, critical software vendors, and key partners.

Write short templates ahead of time for employees, customers, suppliers and partners, and leadership. Only authorized people should talk to the outside about cause, impact, or when service will return.

Test One Scenario at a Time

Short tabletop exercises are enough. Try these:

• The office loses internet during a busy period.
• Power is out for the rest of the workday.
• The phone provider is down.
• A critical cloud application is unavailable.
• A vendor outage runs into the next business day.

Write down the decisions you made, missing contacts, documents you couldn't reach, and assumptions that turned out to be wrong. Give each fix an owner and a date.

No plan promises that every service will always be up. A useful one tells people what matters most, how to keep working without a tool, and how to get back to normal in order.
