Case Study: Unibill achieves uninterrupted billing and business continuity during Hurricane Rita with Vision Solutions' iTera HA

Unibill - Customer Case Study

Unibill, LLC is a Lake Charles–based application service provider that handles real-time billing for telecom and cable customers and requires 24/7 availability and complete data integrity. When Hurricane Rita in 2005 severed the VPN link between its IBM iSeries production system and clients/remote mirror, Unibill risked losing access to customer records and disrupting mission‑critical billing services.

Using Vision Solutions’ iTera HA and an emergency failover to its Dallas IBM System i 520 backup, Unibill and Vision’s support team verified committed transactions and had customers redirect to the backup IP, restoring service quickly. The company ran production from the backup for four weeks with negligible customer impact, maintained business continuity and data integrity, and earned industry recognition and awards for its resiliency.
