Blackberry makers RIM said today that the messaging and browsing delays being experienced by BlackBerry users in Europe, the Middle East, Africa, India, Brazil, Chile and Argentina were caused by a core switch failure within RIM's infrastructure.
Although the system is designed to failover to a back-up switch, the failover did not function as previously tested.
"As a result, a large backlog of data was generated, and we are now working to clear that backlog and restore normal service as quickly as possible. We apologize for any inconvenience, and we will continue to keep you informed."
Thousands of Blackberry users over the past two days could not hook up to the internet because of the RIM faults.
