A widespread service outage affected BlackBerry users across North and South America Tuesday evening.
BlackBerry maker Research in Motion, which is based on Waterloo, Ont., has confirmed there are some email delays.
Would-be users tweeted their frustration on social networking site Twitter. Some said they also couldn't connect to the internet.
A spokesperson for RIM said the company is working to fix the problem, but could give no estimate when service will be restored.
The outage comes on the heels of another BlackBerry email outage in North America that struck on Dec. 17.
