Leased Line Backup
100% service availability with resilient, diversely-routed internet failover — so a cable break, router or ISP fault never takes your business offline.
When it needs to connect, it stays connected.
Connectivity loss can cost a business thousands in lost productivity and revenue. Our leased line backup service protects against cable breaks, router, firewall or ISP failure — automatically switching your traffic to a diverse backup circuit the instant something goes wrong.
Diverse RAO2 fibre
Diversely routed circuits connecting to separate exchanges, ducts and datacentres, protecting against fibre breaks at your premises or beyond.
Smart network monitoring
Our core network monitors your circuits 24/7/365, automatically and seamlessly switching traffic to a backup line the moment a failure occurs.
Dual routers
High-availability router pairs act as one — should a device, port or circuit fail, the secondary router takes over automatically.
Dual firewalls
High-availability firewall pairs configured and managed by our team, so security never fails and you stay connected.
IP SLA & BGP failover
Dynamic BGP routing and IP SLAs seamlessly switch traffic between diverse circuits terminating in different parts of our core network.
Works with any circuit
Backup can pair with leased lines, EoFTTC or business broadband — matched to the resilience your site needs.

RAO2 Standard
Two leased lines from your premises using different routes and ducts to the same telephone exchange — protecting against fibre breaks at your site.
RAO2 Plus
Two leased lines routed to different telephone exchanges, protecting against fibre breaks, exchange failure and datacentre failure.
VRRP router failover
Virtual Router Redundancy Protocol automatically switches traffic to a backup router and circuit if the primary router or line fails.
Active-Active or Active-Passive?
Active-Active
Both circuits carry traffic simultaneously, giving combined bandwidth. If one fails, service continues at reduced speed on the other.
Active-Passive
One circuit is primary; the secondary takes over automatically if it fails, then reconverges once the primary line is restored.
