Downtime is expensive in ways the spreadsheets don't always capture. A law firm that can't access case files for half a day loses billable hours, breaks a court deadline, and apologizes to a partner who won't fully trust the IT setup again for a year. A dental practice with the scheduling system down on Monday morning has 47 angry phone calls and a chaos-spillover into Tuesday.
Here's what actually causes downtime for Savannah small businesses, and what's worth doing about each.
The actual top causes (from our incident log + industry data)
Most "the computers are down" calls trace back to a small list of root causes:
- Internet outage — Comcast Business or AT&T in the area, hurricane-related Gulf storms, or construction crews cutting fiber. Coastal Georgia gets all three.
- Power outage — same Coastal Georgia weather. Even brief power flicker can crash unprotected servers and networking gear.
- Hardware failure — typically a single point of failure (a SonicWall, a single VPN appliance, a desktop running the line-of-business app for everyone).
- Human error — accidental file deletion, wrong DNS change, expired SSL certificate nobody renewed.
- Cybersecurity incident — ransomware, account takeover, compromised email.
- Vendor outage — Microsoft 365, your accounting cloud, your e-signature service.
Notice what's not on the list: anything that's solved by buying a premium-tier managed IT package. The same five or six causes account for the overwhelming majority of "downtime" events. The job is reducing the probability and the recovery time on each one, not buying a bigger product.
What actually moves the needle
Redundant internet
For any business where 30 minutes offline is a problem, you need two ISPs (preferably on different physical paths into the building) and a router that fails over between them automatically. Coastal Georgia businesses often pair Comcast Business or AT&T fiber with a 5G/LTE failover from a different carrier. Total cost is usually $100–$300/month and pays for itself the first time fiber goes down.
Decent UPS on critical gear
A small uninterruptible power supply on the firewall, switch, and any on-prem server costs $200–$500 and rides out the 95% of "outages" that are actually 30-second flickers. Without it, those flickers force a reboot cycle that can take 10–20 minutes to fully recover.
Eliminate single points of failure
If one device going down stops the business, fix that. Examples we see in Savannah:
- A single VPN concentrator everyone connects through. Replace with a mesh VPN (Netbird, WireGuard) so no single device is the choke point.
- One desktop running the practice management software for the whole office. Move it to a virtualized environment with daily backups and failover.
- A single SSL certificate that expires on Christmas Eve. Automate renewal.
Backups that actually restore
We covered this in our cybersecurity post, but it applies double here. The fastest recovery from a ransomware incident, an accidental deletion, or a hardware failure is a tested backup. Untested backups are not backups.
Patching schedule
Critical security patches should be applied within a defined SLA — for our managed IT clients we target 7 days for critical, 30 days for high. The downtime savings from preventing one exploit-driven incident pays for years of patching attention.
Monitoring that wakes someone up
The difference between a 5-minute outage and a 5-hour outage is whether someone got an alert. If your firewall, server, internet, or critical app stops responding, an automated alert system should page a human within 60 seconds. We use a self-hosted monitoring stack (Uptime Kuma + alerting) for our managed IT clients — cheap and effective.
Documented runbooks
When the wrong thing breaks at the wrong time, a panicked Google search makes everything worse. A two-page runbook for "internet is down," "email is down," "server won't boot," and "we got hit with ransomware" cuts recovery time enormously.
Marketing fluff to ignore
A few things you'll be sold that don't usually pay off for a 10-person business:
- "99.999% uptime SLA" on a managed IT contract. The five-nines uptime claim is meaningless without specifying what's measured and the credits aren't usually material. Better to look for clear response-time commitments.
- "24/7 SOC monitoring" for businesses that aren't actually targets of advanced threats. A small dental practice in Pooler doesn't need a SOC — they need EDR with alerts that get reviewed during business hours, plus a clear escalation path.
- Enterprise high-availability clusters for line-of-business apps that 8 people use. Daily backups and a 4-hour RTO are almost always the right answer at this scale.
What we recommend for Savannah small businesses
A practical starter package:
- Dual-ISP with automatic failover
- UPS on firewall + switch + any on-prem server
- Replace any single-VPN-appliance setup with a mesh VPN
- Backups: daily, encrypted, immutable off-site, tested quarterly
- EDR on every endpoint
- Automated patching with a defined SLA
- Uptime monitoring with alerts to a real human
- Two-page incident runbook customized to your stack
Most of this is configurable in a few weeks for a typical 5–30 person Savannah business. Cost is well inside a normal IT budget, and the payback on the first prevented incident usually covers a year of the program.
