Not since April of 2007 have we seen a Blackberry outage this major. Over ten million Blackberry customers are out in the Americas at the moment and this is regardless of service provider. RIM is having consistent problems with this device. By consistent I mean when your network outages are annual or more often, there are obvious systemic problems that need to be resolved.
Having said that… The e-mail and spam of some of the most important people in the world go through a single company’s network… There are likely few other companies who have to deal with what RIM does and hopefully they will get these problems solved quickly.
