Worldspan, a provider of technology resources for the travel industry, e-commerce sites and corporations, has signed a five-year, multi-million dollar contract for managed networking services and data vaulting technology with AT&T.

Worldspan already used AT&T for voice and data services. The new agreement calls for AT&T to provide redundant, geographically diverse, networked-based data storage.

Worldspan offers fares and pricing technology, trip management and other services. It is based in Atlanta.

“By strengthening our computer system capability infrastructure through AT&T’s support, we will be able to virtually guarantee network efficiency and dependable access to data,” said David Lauderdale, chief technology officer for Worldspan, in a statement.
