UK’s mobile phones and broadband provider O2 has blamed Ericsson’s centralized user database (CUDB) as responsible for second network outage within four months.
The firm revealed that Ericsson’s technical fault had led to affect nearly 10% of its 23 million customers for 20 hours and mobile operator was forced to apologise.
O2 chief operating officer Derek McManus said that the firm is removing the Central User Database provided by the supplier, 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," McManus said.
During the first outage affect in July, O2 had recompensed its customers with a 10% percent bill discount.
An Ericsson spokeswoman was quoted by The Guardian as saying that the firm has worked closely with its customer to identify any contributing factors and immediately took necessary actions.
"The issue was identified to be related to how the equipment was configured," spokeswoman said.

"We continue to work closely with O2 to ensure that service integrity is maintained."
Ericsson’s database technology enables SIM cards to roll to O2’s network and provides users with access to the network.
The technology will also collect data in a single place and offer firm with easy access to user details.
"We will be committing an additional spend of £10 million on this change, and will also continue to invest £1.5m a day on building out and improving our network," McManus said.
