Blackberry’s founder Mike Lazaridis has said services are “fully restored” following a three-day global blackout.
Millions of customers worldwide had their messaging and email service disrupted with many turning to Twitter to express their anger.
In a press conference, Lazaridis said the company would now begin a full investigation of what happened.
He apologised again for the problems customers had experienced.
“We know we’ve let many of you down. You expect more from us. I expect more from us,” he said.
The firm admitted that it was the largest crash it had ever experienced. Prior to the 2011 problems, the last significant blackout was in 2009.
The next priority would be a “root cause analysis” of why there was a core switch failure within RIM’s infrastructure.
“We don’t know why the switch failed and why the back-up didn’t function as it should,” said Lazaridis.
In a question and answer session following the press conference, RIM declined to discuss whether it would be compensating users.
Some operators, such as Telefonica owner of the UK’s O2, are mulling whether to provide compensation for affected users.
Users began to report loss of services mid-morning on 10 October and the problems spread around the world. (BBC)
