BlackBerry customers on T-Mobile USA's network west of the Mississippi River lost e-mail service for nearly two hours Monday afternoon when a component in a router failed.
The component handled only BlackBerry e-mails, so other T-Mobile services such as phone calls were unaffected. The e-mail service went out about 4 p.m. Pacific time and was restored by 5:45 p.m., T-Mobile spokesman Peter Dobrow said.
The outage, though covering half the nation geographically, did not affect all BlackBerry customers -- only those on T-Mobile's network.
Dobrow would not say how many customers might have been affected.
Executives at BlackBerry's Canadian maker, Research in Motion Ltd., could not be reached for comment.
Earlier this year, BlackBerry owners throughout the country got 14 hours of, perhaps, unwanted relief from thumbing the tiny keyboards on the addictive devices that have become known as CrackBerrys when an upgrade by Research in Motion went awry and triggered a series of glitches that led to a major outage.
The company would not explain for several days what went wrong.
