LONDON - E-mail and messaging glitches that have plagued BlackBerry users around the world for a second day were caused by a core switch failure, the smartphone’s maker said yesterday.
Research in Motion Ltd. said the disruptions, which affected users from Europe to Latin America, were due to a failure within the company’s own infrastructure. A transition to a back-up switch did not function as tested, causing a large backlog of data, RIM said.
It was the first time the company offered an explanation of the outage since problems first occurred Monday morning.
The disruptions affected BlackBerry users in Europe, the Middle East, Africa, India, Brazil, Chile, and Argentina.
RIM said early yesterday that the problems were resolved and that services were operating normally, but hours later it acknowledged that the disruptions were continuing.
RIM, based in Waterloo, Ontario, apologized for “any inconvenience,’’ as Twitter and the Internet lit up with condemnation over a delayed response to problems some users had reported for hours.
There were no reports of any problems in the United States.
