BlackBerry maker Research In Motion was investigating reports some users experienced delays, but said on Wednesday it was not fighting an outage similar to the one that took down its service for four days last month.

"We're getting reports that some users are experiencing delays. We're investigating and will update you ASAP," the company said on its official Twitter account.

A company spokeswoman added: "There is no system-wide outage. However, we are investigating reports that some users in EMEIA have experienced delays," referring to Europe, the Middle East, India and Africa.

Later on Wednesday, the company said BlackBerry services "are currently operating normally" in those regions. Last month, a failure in RIM's unique server architecture, which compresses and encrypts mobile data, cut off email, Internet and messaging service for millions of BlackBerry users across five continents for up to four days.

That fault occurred in a facility in England, initially affecting Europe and surrounding regions before spreading to North and South America.  - Reuters
