Co-CEOs Mike Lazaridis and Jim Balsillie informed investors and reporters on a conference call that the service to all BlackBerry customers in all regions of the world had been restored as of the wee hours of Thursday morning.
Lazaridis explained in slightly more detail what caused the problem. And he once again apologized to customers. Earlier on Thursday the company released a taped video apology from Lazaridis.
"Our inability to quickly fix this has been frustrating," he said.
He explained that on Monday there was a hardware failure on a dual redundant-core switch that had been designed to help protect the BlackBerry infrastructure that failed. This switch failure caused the e-mail and messaging services to go down in Europe, India, Africa, the Middle East, and parts of South America.
The backup switching architecture did not work as intended and the systems in Europe quickly became overwhelmed, which is how the issue began rippling to other parts of the world. When technicians restarted the system, it took a long time for the backlog of messages and data passing through the infrastructure to become stable.
Now that service is restored, customers should be seeing inboxes on their BlackBerry smartphones fill up with messages that had been sent and queued up in the system.
