An international interruption in BlackBerry services is now affecting North America, which means that a majority of people inside offices on Capitol Hill and along K Street are probably running around wondering if they should crack each other’s heads open and feast on the goo inside.

[BlackBerry manufacturer Research in Motion], which had said on Tuesday services had returned to normal, said later it was still working to resolve the problem.

“The messaging and browsing delays … were caused by a core switch failure within RIM’s infrastructure,” it said. “As a result, a large backlog of data was generated and we are now working to clear that backlog and restore normal service.”

RIM did not say how long it might take.

You know, I hear that there’s a device coming out at the end of this week that could be a viable alternative.
