For most accounting firms, an Internet outage can interrupt access to Microsoft 365, cloud accounting platforms, tax applications, document management systems, VoIP phones, remote access, and client portals within minutes.
A practical Internet continuity strategy should address five areas: identifying Internet-dependent systems, establishing backup connectivity, designing network failover, documenting outage procedures, and testing the solution before a critical deadline.
For a 5 to 25 employee accounting firm, the goal is not necessarily to make an Internet outage invisible. The goal is to determine which business functions must continue, how quickly connectivity needs to be restored, and what level of backup connectivity is appropriate for the firm's operational risk.
During tax season, those questions become especially important.
Why Internet Connectivity Has Become Business-Critical Infrastructure
Years ago, an Internet outage might have meant employees temporarily could not browse websites or send email.
For many accounting firms today, it can mean employees cannot work.
Consider how many common business systems may depend on Internet connectivity:
- Microsoft 365
- Cloud-based tax applications
- QuickBooks Online and other accounting platforms
- Client portals
- Document management systems
- Cloud file storage
- VoIP phone systems
- Remote access
- Banking websites
- Payroll platforms
- Identity and authentication services
- Cloud backup systems
Even applications running locally may have Internet dependencies for authentication, licensing, integrations, updates, or access to external data.
This creates an important operational question:
What happens to your firm when the primary Internet connection fails?
The answer should be known before the outage occurs.
A Five-Part Internet Continuity Framework for Accounting Firms
Internet resilience does not start by simply ordering a second Internet connection.
A useful strategy starts with the business requirements and then determines what technology is necessary to support them.
1. Identify Which Business Functions Depend on the Internet
Start by identifying what actually stops working when Internet connectivity is lost.
For each critical application or service, ask:
- Does it require Internet access?
- How many employees depend on it?
- Can employees perform useful work without it?
- Does it support client-facing services?
- Is it particularly important during tax season?
- How long can it reasonably be unavailable?
This exercise can reveal dependencies that are not immediately obvious.
For example, an application may run on a server inside the office but still require Internet access for authentication.
A phone system may depend entirely on Internet connectivity.
Employees may have access to locally stored files but still be unable to communicate with clients or access cloud applications.
The objective is to understand the business impact, not merely confirm that the Internet is unavailable.
Example: A 15-Person Accounting Firm
Consider a 15-person accounting firm where employees depend on Microsoft 365, a cloud-hosted tax application, VoIP phones, and a client document portal.
If the Internet connection fails:
- Email access may be disrupted on office computers.
- Employees may lose access to the tax application.
- Client documents may become unavailable.
- Desk phones may stop working.
- Client portal activity may be interrupted.
The firewall, computers, and applications themselves may all be functioning correctly.
The problem is that a single connectivity failure has interrupted access to multiple business services.
That is why Internet connectivity should be evaluated as part of the firm's overall technology resilience.
2. Determine How Long the Firm Can Operate Without Connectivity
The next step is establishing the business requirement.
Ask:
How long can the firm reasonably operate without its primary Internet connection?
The answer may change throughout the year.
A two-hour Internet outage on a quiet afternoon may be inconvenient.
A two-hour outage immediately before a major filing deadline may create a much greater business impact.
Accounting firms should consider factors such as:
- Number of employees affected
- Billable work interrupted
- Client deadlines
- Phone availability
- Access to client records
- Remote employee connectivity
- Ability to communicate with clients
- Time of year
Understanding the business impact of technology downtime can help leadership determine whether an outage measured in minutes or hours represents an acceptable risk. The objective is not necessarily to assign an exact dollar value to every outage.
It is to determine whether Internet access is important enough that waiting several hours for an ISP technician is an acceptable recovery strategy.
For many firms, it will not be.
3. Consider Backup Internet for Your Accounting Firm
One of the most direct ways to reduce Internet outage risk is to provide another path to the Internet.
That could include:
- A second wired Internet provider
- Cable plus fiber
- Fiber plus cable
- Fixed wireless
- Cellular connectivity
- 5G backup service
The appropriate solution depends on the firm's location, connectivity options, bandwidth requirements, and tolerance for downtime.
But there is an important detail:
Two Internet connections do not automatically mean true redundancy.
Suppose a firm purchases Internet service from two providers, but both services enter the building through the same physical pathway.
Construction damage to that pathway could potentially interrupt both connections.
Likewise, two services may ultimately depend on shared upstream infrastructure.
Perfect carrier diversity is not always practical for a small accounting firm, but these dependencies should at least be understood.
Wired Backup vs. Cellular Backup
A secondary wired connection may provide more bandwidth and potentially support normal operations during a primary outage.
Cellular or 5G connectivity may be easier to deploy and can provide a different physical path from traditional wired service.
But cellular performance can vary based on:
- Signal strength
- Building construction
- Network congestion
- Carrier coverage
- Data limits
- Number of connected users
The question is not simply:
Do we have backup Internet?
The better question is:
Can the backup connection support the business functions we expect it to support?
4. Configure Automatic Failover and Traffic Priorities
Having backup Internet available is useful.
Having it automatically take over when the primary connection fails is much better.
A properly configured business firewall can often monitor the primary Internet connection and route traffic through a secondary connection when necessary.
This is commonly referred to as WAN failover.
The process might look like this:
Normal operation: Primary Internet connection carries business traffic.
Primary connection fails: The firewall detects the failure.
Failover: Traffic is routed through the secondary connection.
Primary service returns: The firewall detects that service has been restored and transitions traffic according to its configuration.
The exact behavior depends on the firewall, Internet services, and network design.
Not Everything Needs Equal Priority
Backup bandwidth may be more limited than the firm's primary connection.
That means the firm may need to prioritize critical traffic.
For example, during failover, priority might be given to:
- Tax applications
- Microsoft 365
- Client portals
- VoIP communications
- Remote access
- Critical cloud applications
Meanwhile, activities such as large software downloads, operating system updates, streaming media, or other nonessential traffic could be limited.
The objective is to preserve business-critical operations, not necessarily reproduce the firm's normal Internet experience perfectly.
5. Document and Test the Failover Process
A backup connection that has never been tested creates the same problem as an untested backup.
You know the technology exists.
You do not necessarily know that it will work when needed.
Internet failover should be tested periodically.
A basic test might confirm:
- The primary Internet connection is disconnected.
- The firewall recognizes the outage.
- The secondary connection becomes active.
- Critical applications remain accessible.
- DNS resolution continues functioning.
- VoIP or other communication services behave as expected.
- Remote access works where required.
- The network returns to normal when primary service is restored.
Testing may reveal unexpected dependencies.
For example:
A cloud application may restrict access based on the firm's public IP address.
A VPN configuration may depend on the primary connection.
A phone system may not transition as expected.
The backup connection may work but provide insufficient bandwidth for all employees.
These are much better problems to discover during a scheduled test than during a filing deadline.
The same principle applies to broader recovery testing: having backup technology in place is different from proving that it works under realistic conditions.
What Should Employees Do During an Internet Outage?
Technology is only part of the continuity plan.
Employees should know what to do when connectivity problems occur.
A simple procedure might include:
Step 1: Report the problem
Employees should know how to contact IT even if email or VoIP is unavailable.
Step 2: Confirm the scope
Determine whether the issue affects one computer, one application, the office network, or the Internet connection itself.
Step 3: Activate or verify backup connectivity
If automatic failover is configured, confirm that it occurred successfully.
Step 4: Prioritize critical work
If backup bandwidth is limited, employees may need to temporarily avoid nonessential Internet activity.
Step 5: Communicate status
Leadership and employees should receive clear updates about the outage and any temporary operating procedures.
This does not require a complicated manual.
A short, documented procedure with clear responsibilities is often more useful than a 30-page document nobody can find during an outage.
Why a Mobile Hotspot Is Not Always a Business Continuity Strategy
When Internet service fails, someone may suggest:
"We'll just use our phones."
For one employee who needs temporary email access, that may work.
For an entire accounting firm, it may not.
Personal hotspots can introduce limitations involving:
- Bandwidth
- Signal quality
- Battery life
- Device limits
- Security
- VPN connectivity
- Printer access
- Shared resources
- Employee availability
There is also a significant difference between an improvised workaround and a tested business continuity solution.
A hotspot can certainly be part of an emergency plan.
But if leadership expects 15 employees to continue normal operations through personal phones during tax season, that assumption should be tested before it becomes the actual recovery strategy.
Internet Redundancy Does Not Solve Every Outage
Backup Internet improves resilience, but it should not create false confidence.
Employees can still lose access to technology because of:
- Firewall failure
- Network switch failure
- Wireless infrastructure failure
- Power outage
- DNS problems
- Identity service disruption
- Microsoft 365 outage
- Cloud provider outage
- Application failure
- Cybersecurity incident
This is why Internet continuity should be one component of a broader business continuity and disaster recovery strategy.
A second Internet connection cannot restore a failed server.
A backup cannot fix a failed firewall.
A functioning network cannot make an unavailable cloud application come back online.
Production Readiness requires understanding how these components depend on one another.
What About Employees Working From Home?
Remote work introduces another consideration.
An employee working from home typically depends on:
- The employee's home Internet connection
- Their computer
- Identity and authentication services
- Cloud applications or remote access
- Potentially the accounting firm's office connectivity
Depending on the firm's architecture, an office Internet outage may or may not affect remote employees.
For example, employees accessing Microsoft 365 directly from home may continue working even when the office loses connectivity.
But if they need to connect through the office to reach a local application, the office outage could still affect them.
This is another reason the firm should map dependencies rather than assuming that "everything is in the cloud" or "everyone can work from home" automatically solves continuity concerns.
Internet Resilience Before Tax Season
Tax season changes the business impact of technology failure.
That makes the period before peak production a good time to confirm:
- Primary Internet service is stable
- Backup connectivity is operational
- Automatic failover works
- Critical applications function through the backup connection
- Firewall configurations are current
- Vendor contact information is documented
- Employees know how outages will be communicated
- Known connectivity issues have been addressed
For firms that depend heavily on cloud applications, Internet connectivity deserves the same operational attention as servers, backups, authentication, and endpoint security.
The technology may be different.
The operational principle is the same:
Identify the dependency, monitor it, test it, and know what happens when it fails.
Internet Continuity Is Part of Production Readiness
At Everleap IT, we view Internet resilience as one component of operating a Production Ready technology environment.
The goal is not to purchase redundant technology simply because redundancy sounds good.
The goal is to understand the firm's operational requirements and design technology accordingly.
For one accounting firm, that might mean a secondary cellular connection that supports only essential applications.
For another, it might mean two business-class Internet circuits with automatic failover.
For another, the right decision may be accepting a limited amount of downtime because the business impact does not justify additional infrastructure.
A Production Ready approach connects the technology decision to the business requirement.
How Everleap IT Approaches Connectivity and Resilience
Our approach has been shaped by more than 20 years of operating production hosting environments, where network connectivity, redundancy, monitoring, capacity, recovery, and availability are everyday operational concerns.
For accounting firms, that same mindset can be applied through:
- Internet connectivity planning
- Firewall management
- Network monitoring
- Failover configuration
- Business continuity planning
- Disaster recovery
- Infrastructure lifecycle management
- Strategic technology planning
- Production Readiness assessments
The objective is not to promise that technology will never fail.
The objective is to understand critical dependencies, reduce avoidable single points of failure, and prepare the organization to continue operating when disruptions occur.
Is Your Accounting Firm Prepared for an Internet Outage?
A simple starting point is to answer five questions:
- Which critical business systems stop working if the Internet fails?
- How long can the firm operate without those systems?
- Do we have an alternate Internet connection?
- Will critical applications actually work over that connection?
- When did we last test it?
If the answers are unclear, the firm may have an Internet continuity gap worth addressing.
Everleap IT helps accounting firms throughout California's Inland Empire, including Rancho Cucamonga, Ontario, Claremont, and nearby communities, improve technology resilience through proactive monitoring, network management, connectivity planning, business continuity, disaster recovery, strategic planning, and Production Readiness assessments.
