Failover internet explained for UK businesses. How it works, what it protects, how quickly it activates and whether your business needs it.
Failover internet is a backup connection that automatically activates when your main broadband or leased line stops working. Think of it like a generator for your internet — when the primary supply fails, the backup cuts in automatically, keeping your business running.
Assure X uses a dual-WAN router that monitors your primary connection continuously. When it detects a fault — whether it's a fibre cut, cabinet fault, router issue or Openreach maintenance window — it automatically switches all your business traffic to a 4G or 5G backup connection in under 60 seconds. When the primary connection recovers, traffic switches back automatically. No manual intervention at any point.
Ten years ago, most business operations could tolerate a few hours offline. Today, almost no UK business can function without internet access. Cloud-based accounting, hosted phone systems, card payments, booking systems, email, Teams calls — all of it stops when the internet goes down. The average UK broadband outage lasts 4–8 hours. For a business processing £500/hour in revenue, that's a £2,000–£4,000 event. Assure X costs from £29/month.
Mobile data on your phone only helps you personally — your office systems, card machines and VoIP phones are still offline. Assure X connects at the router level, so every device in your office continues working through the failover connection.
The Assure X router arrives pre-configured. Self-installation takes under 30 minutes. On-site installation by a Telexico engineer is also available across the Midlands.
There may be a brief 60-second pause as the router switches connections. After that, everything continues normally. Telexico sends you an SMS and email alert immediately so you know what's happening.
Yes — Assure X protects any primary connection: broadband, leased line, private fibre. Adding failover to a leased line gives you the guaranteed performance of a leased line with the resilience of 4G backup.
