Ericsson has confirmed that a fault with its software was the source of yesterday's massive network outage, which took millions of smartphones offline across the UK and Japan and created issues in almost a dozen countries. From a report: In a statement, Ericsson said that the root cause was an expired certificate, and that "the faulty software that has caused these issues is being decommissioned." The statement notes that network services were restored to most customers on Thursday, while UK operator O2 said that its 4G network was back up as of early Friday morning.

Softbank said that the outage affected its own network for just over four hours.
