Why office-based businesses need internet failover. Cloud software, VoIP, VPN access and the true cost of a half-day outage for a professional services team.
Consider what an average office worker needs internet access for: Microsoft 365 documents, Teams calls, email, cloud-based CRM, web-based accounting software, VoIP phone calls, video conferencing and file storage. Every single item on that list requires a live internet connection. This wasn't true five years ago. It absolutely is now.
A 20-person professional services office billing at £100/person/hour loses £2,000 for every hour of internet downtime during business hours. A 4-hour outage — typical for a broadband fault — costs £8,000. For law firms, accountancy practices and consultancies where billable hours are the entire business model, this is not a theoretical concern.
Many offices now run hybrid models — some staff in the office, some remote, connecting via VPN. When office broadband fails, VPN tunnels drop. Remote staff lose access to office systems. Shared document collaboration stops. Teams calls to office numbers go dead. A single broadband fault creates a cascade of problems across the entire distributed team.
Assure X installs in under 30 minutes alongside your existing connection. When the primary broadband detects a fault, traffic automatically routes via 4G/5G backup within 60 seconds. VoIP phones, VPN connections, Teams calls, cloud software — all continue normally. Staff may notice a brief pause; in most cases they don't notice at all. Telexico's monitoring sends you an immediate alert so you know what's happening and why.
Yes — VPN connections resume on the 4G/5G backup connection after the brief 60-second switchover. For organisations requiring seamless VPN continuity, a static IP on the failover SIM ensures the VPN configuration doesn't need to change.
Active Teams calls may drop during the 60-second switchover period. New calls connect normally on the failover connection immediately after. Teams is entirely functional on a 4G failover connection.
An office of 10 people running Teams, 365 and cloud CRM for 4 hours on failover typically consumes 5–15GB. A 20GB Assure X plan provides comfortable headroom for full working-day failover events.
Yes — Assure X works with any primary connection. Adding 4G failover to a leased line provides a very strong resilience combination: leased line performance day-to-day, 4G backup if the leased line ever develops a fault.
