LONDON — Email 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 Tuesday.
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.
“We are now working to clear that backlog and restore normal service as quickly as possible,” the company said in a brief statement.
The disruptions affected Blackberry users in Europe, the Middle East and Africa, India, Brazil, Chile, and Argentina.
RIM said early Tuesday that the problems were resolved and that services were operating normally, but hours later it acknowledged that the disruptions were continuing.
