RIM Explains Blackberry service failure
“The delays in surfing and messaging that Blackberry users have experienced in Europe, Middle East, Africa, India, Brazil, Chile and Argentina have been caused by a faul in a switch core at RIM infrastructure. Although the design of the system was prepared for failure, the failover did not work as expected. As a result, a large backlog of data was generated and we are working to restore service as soon as possible” that is the message that Research In Motion (RIM) has given to its users in a statement.
When RIM tried to solve the problem, the slope of accumulated traffic study was such that, when applying the balancing on the other servers, they collapsed and became a bottleneck that extended beyond the EMEA territory (which suffered the failure on the first day).
It has been three days since the blackberry service problems started and already spread across four continents, depriving Blackberry users of internet services and instant messaging, they are only able to make calls and send sms until the problem is resolved.
