BlackBerry subscribers throughout the world continued disruptions in service from 3 consecutive days because of the a problem with Research In Motion’s [RIM] equipment in its data centers. Users from Europe, Africa, India, Brazil and Chile are experienced an email, messaging and Web surfing outage from past 3 days. Now the problem seems to spreed to Canada and US.  One user in the Boston area said he began seeing email delays early Wednesday morning. And when batches of email arrived, they were about three hours old.

We apologize for any inconvenience and we will continue to keep you informed.”[/box_dark]

RIM’s BlackBerry network architecture is its strength as well as its biggest weakness. BlackBerry use a centralized architecture called RMI which routes all e-mail and messaging traffic through its BlackBerry servers network operation centers all over the world. If there is a error or failure at any point in the centralized architecture, then the services around the world are effected.
