Automatic failover
The router or firewall detects a drop and shifts traffic to the secondary line without anyone unplugging cables.
Internet Access
Internet Resilience
One line is one point of failure, and most businesses only discover what that costs on the morning it goes down. Resilience keeps the payments, the phones and the cloud systems trading, and tells you in advance which services will survive and which will simply wait.
What this protects
Keeping the revenue-critical systems online
When the main line fails, you decide what stays up. Get that decision right in advance and an outage is an inconvenience rather than a lost trading day.
A second path that works
Automatic failover to a fixed backup line or 4G/5G, so the services you rely on keep running without anyone unplugging cables.
Priorities agreed, not guessed
We agree what must stay live, payments, phones and cloud, so the switch is decided calmly rather than in the middle of an outage.
Tested, not assumed
Scheduled failover tests prove the backup carries the load you expect, because a failover nobody has triggered is a theory rather than a safeguard.
Failover that only fails over what you choose
A single internet line is a single point of failure, and most businesses only discover that when it goes down. Resilience means having a second path that takes over when the first one falters.
The detail most providers gloss over is that failover is selective. You decide what is critical enough to move to the backup link and what can wait. A 4G link may be plenty for VoIP, email and card payments, but not for pulling a large backup at the same time.
We design that on purpose. The firewall or router watches the primary line, detects a failure, and shifts the traffic you have chosen onto the secondary connection automatically. Then we test it, because a failover nobody has ever triggered is a theory rather than a safeguard.
4G and 5G are genuinely useful backup paths now, not a gimmick. Speeds are often good enough to carry a whole small office, and coverage is checked at your premises so we know the backup will actually work where you sit.
How we build resilience
4G and 5G backup
A mobile router with a roof or window antenna as a genuinely usable second path, not a token gesture.
Dual fixed lines
A second physical circuit, ideally from a different carrier or route, so one cable cut does not take you out.
Priority routing
We agree what matters most, then fail those services over first while the rest waits politely.
Testing
Scheduled failover tests confirm the backup actually carries the load you expect from it.
Monitoring
Both paths are watched for latency and packet loss, so you hear about degradation before a full outage.
What good resilience looks like
- Every critical service tested over the backup path before you rely on it
- The switch to backup happening automatically rather than because someone noticed
- A backup connection that is monitored, so a silent failure is caught early
- Clear priorities agreed in advance rather than decided in the middle of an outage
- The PSTN switch-off considered, because legacy phone and alarm lines are affected by it
Questions we get asked about Internet Resilience
Not always, but many businesses choose one anyway. A lease line is highly reliable, yet construction work or a cable fault can still take it out. A 4G failover is inexpensive cover for the services that matter most.
Often fast enough to carry a small office entirely, though it depends on coverage at your location. We test the signal where you actually sit, not on a coverage map.
Whatever you have chosen. We agree a list of priority services with you, so payroll, payments and phones stay up while non-critical traffic can wait.
Usually not, if it is set up properly. The switch takes seconds and connections recover, though a call in progress mid-failover may drop.
Yes. We run scheduled failover tests out of hours or at a quiet moment, and report what succeeded and what needs attention.
