O2 has said it its ripping out its Ericsson CUD systems after two failures caused loss of services to customers resulting in reputational and financial damage to the operator.
“(O2) CTO Derek McManus, writing on a company blog, said, “We are removing the Central User Database provided by one of our suppliers, which has suffered two different faults in the last few months. We are not prepared to risk this happening to our customers for a third time and are implementing a proven alternative solution.” That central user database refers to the Ericsson-supplied database that was blamed by O2 for its July outage. ”
