The CDK outage made one thing clear for dealerships: a major vendor failure is not just an IT issue. It can affect sales, service, parts, accounting, customer communication, financing, repair orders, appointments, payroll, and management visibility.
Every dealership should have a continuity plan for the systems that keep the store operating when the DMS, internet, phones, payment systems, or a key vendor is unavailable.
Map Critical Workflows
Start with the work that must continue during an outage.
- New and used vehicle sales.
- F&I and lender communication.
- Service write-up and repair order handling.
- Parts lookup and ordering.
- Customer appointments and follow-up.
- Payment processing.
- Payroll and time clocks.
- OEM warranty and incentive workflows.
- Internal communication between managers and departments.
For each workflow, identify the system of record, the backup process, who owns the workaround, and what must be reconciled later.
Identify Single Points Of Failure
Dealerships often discover dependencies only after they break.
- One internet circuit supporting the entire rooftop.
- One firewall with no current configuration backup.
- One DMS or CRM vendor handling multiple departments.
- One phone system or call tracking vendor.
- One remote access path for managers and vendors.
- One unmanaged switch or network closet that everything crosses.
- One person who knows how a workaround works.
The goal is not to eliminate every dependency. The goal is to know which ones can stop the store and what the first move should be.
Prepare Department Runbooks
Each department needs a simple outage procedure.
- Sales: inventory access, quote process, customer follow-up, document capture.
- F&I: lender communication, credit application handling, secure document storage.
- Service: appointment list, write-up process, customer authorization, parts coordination.
- Parts: lookup process, emergency ordering, counter sales.
- Accounting: daily close, deposit handling, payable/receivable dependencies.
- Management: status updates, vendor escalation, customer messaging, recovery tracking.
Runbooks should be short enough to use under pressure. A binder nobody opens is not a plan.
Keep Infrastructure Documentation Current
During an outage, technicians need facts quickly.
- ISP circuit IDs, account numbers, handoff locations, and support contacts.
- Firewall, switch, WiFi, phone, camera, and UPS inventory.
- Network diagrams and VLAN notes.
- Rack photos and patch panel maps.
- Vendor contacts and escalation paths.
- Admin portal URLs and account ownership.
- Backup locations for key configurations.
If the MDF or IDF is undocumented, the continuity plan is already weaker than it looks.
Secure The Workarounds
Manual processes and emergency access can create new risk.
- Do not move customer financial information into personal email or unmanaged file shares.
- Limit who can access manual deal paperwork and scanned documents.
- Track temporary vendor access.
- Require MFA even during emergency work.
- Reconcile paper or offline records after systems return.
- Preserve incident notes and decisions.
Continuity does not mean lowering security until the problem goes away.
Test Before The Next Incident
A dealership should periodically walk through likely outage scenarios.
- DMS unavailable for one business day.
- Primary internet circuit down.
- Phone system unavailable.
- Ransomware concern on a workstation fleet.
- Vendor remote access disabled.
- Service-lane WiFi or tablet failure.
- Camera or access control outage.
The test does not need to be dramatic. A tabletop review with department managers often exposes the most important gaps.
Standard Infrastructure helps dealerships turn outage lessons into practical infrastructure work: cleaner MDF/IDF rooms, stronger network documentation, safer vendor access, better endpoint standards, and clearer recovery procedures. Start with a dealership IT assessment if your store needs a plan that matches how dealerships actually operate.
