Fibre failover for Cape Town businesses, so an outage does not stop trading.
Fibre failover is a second internet path, usually 5G/LTE, that takes over automatically when your primary fibre line drops. Redundant connectivity goes further and combines fibre, microwave and 5G/LTE so that no single link is a single point of failure. Innovo Networks designs, installs and monitors both for Cape Town businesses.

A second path that takes over on its own.
Most businesses run one fibre line. If it fails, voice calls drop, card payments stop and cloud applications become unreachable. A properly configured dual-WAN router switches to a SIM-based backup within seconds, often without anyone in the office noticing. Bonded internet goes a step further by using every link every day.
- Automatic 5G/LTE failover alongside your fibre line
- Bonded fibre, microwave and 5G/LTE as one pool of bandwidth
- UPS sizing for router, ONT and switch as standard on connectivity installs
- Proactive 24/7 network monitoring

UPS, failover or bonded: what each one protects.
| UPS on your network equipment | Automatic 5G/LTE failover | Bonded internet | |
|---|---|---|---|
| What it does | Keeps your router, ONT and switch powered through a load shedding window | Switches to a SIM-based backup when the primary link drops | Combines two or three links into one pool of bandwidth |
| Protects against | Your own equipment losing power at your site | A fibre fault or an upstream outage | A fibre fault or degraded link, with traffic shifting automatically |
| What it does not cover | A fibre cut or an upstream power failure at your provider | Speed depends on tower proximity, congestion and the router used | Needs two or more links and a bonding appliance or SD-WAN service |
| Day-to-day use of the second link | Not applicable | Idle until the primary fails | Used continuously |
| Good fit for | Every site with fibre | Card payments, hosted PBX, cloud applications | Video PBX and call centres, cloud-heavy teams, multi-branch sites |
| How pricing works | Sized and quoted per site | Quoted per site | Quoted per site |
These options work together. A UPS keeps your own equipment alive, failover covers link failure, and bonding adds capacity and resilience.
Three places where power loss can take fibre offline.
Your premises equipment
The ONT and router at your site lose power as soon as your area is load shed. This is the most common failure we see.
Your provider's local exchange
If the fibre network operator's equipment in your area is not on generator or adequate battery backup, the fault sits upstream of you.
Backbone infrastructure
Less commonly affected, since major operators generally run generator backup at core sites, but not guaranteed at every distribution point.
Designed around your site and your risk.
Assess the site
We test coverage at your specific site before recommending 5G/LTE as a failover or primary link.
Size the UPS
Backup for your router, ONT and switch, sized for your network core rather than the whole office.
Add failover or bonding
Automatic 5G/LTE failover, or bonded fibre, microwave and 5G/LTE where downtime is genuinely costly.
Monitor
Our network operations centre monitors the link so resilience is not a one-time setup.
Matched to what an outage costs you.
We do not publish a single price for failover because it depends on your site: the connection you already have, the coverage at your location, whether you need failover or a bonded pool, and the UPS capacity required. A retail store taking card payments has a different risk profile to a back-office admin team, and the investment should match. Call 021 811 3333 or request a quote.
Treat load shedding as a design constraint.
Load shedding is frequent, partially predictable and often affects some sites while others stay powered. Network designs built only for everything down, then everything back up do not reflect that. We recommend tiering systems by importance and power dependency, adding redundant connectivity paths, and testing against realistic outage patterns.

Frequently asked questions.
What is fibre failover?
Fibre failover is a second internet path, usually 5G/LTE, that takes over automatically when your primary fibre line drops, so voice calls, card payments and cloud applications keep working.
Does fibre work during load shedding?
Fibre itself does not need electricity to carry light, but the equipment along the path does: your router and ONT, and your provider's network equipment. If your router and ONT lose power at your site, you lose connectivity even though the fibre signal is live.
How fast does failover switch over?
A properly configured dual-WAN router switches to the SIM-based backup within seconds, often without anyone in the office noticing.
What is the difference between failover and bonded internet?
Failover keeps a second connection idle until the primary fails. Bonded internet uses two or more connections at the same time through a bonding appliance or SD-WAN service, so you get the combined bandwidth every day and traffic shifts automatically if a link degrades.
Is 5G/LTE good enough as a backup?
For almost every business it is the simplest way to add automatic failover. Tower proximity, network congestion and the router used all affect real-world speed, so we test at your specific site before recommending it.
Does a UPS replace failover?
No. A UPS keeps your own router, ONT and switch powered through a load shedding window, but it does not help if the fibre link itself fails. Failover covers link failure, so the two work together.
How much does failover cost?
Pricing depends on your site, the connection you already have and the backup you need, so we do not publish a single price. Request a quote or call 021 811 3333.
