The full extent of the outage to Research In Motion’s BlackBerry’s email service remains unclear, although the worst of the troubles appear to reside in the US.
Comments from European operators suggest the outage hasn’t affected BlackBerry users on this side of the Atlantic, and a RIM official contacted in France said she was unaware of the problems. The official said she had received messages sent to her BlackBerry as normal. Other RIM officials did not return calls seeking comment.
The outage may have been caused by one of RIM's Network Operating Centers (NOC) going down, according to Emma Mohr-McClune, principal analyst with Current Analysis. "This has happened before," she said.
RIM operates two NOCs, both located in Canada, according to Mohr-McClune. The company has considered locating additional NOCs outside of Canada, she said.
Companies that provide BlackBerry service connect their mail servers to a BlackBerry Enterprise Solution (BES) server located on their premises, which in turn is linked to one of RIM's NOCs, according to Mohr-McClune. "All data slides to Canada and back," she said.
