Update: BlackBerry's President and CEO, Thorsten Heins, has issued a statement apologising for the blackout earlier today.
He said: "I want to apologize to those BlackBerry customers in Europe and Africa who experienced an impact in their quality of service earlier this morning.
"The BlackBerry service is now fully restored and I can report that no data or messages were lost. Up to 6 percent of our user base may have been impacted.
"Preliminary analysis suggests that those customers may have experienced a maximum delay of 3 hours in the delivery and reception of their messages.
"We are conducting a full technical analysis of this quality of service issue and will report as soon as it concludes. I again want to apologize to those customers who were impacted today."
Original story: BlackBerry has once again been hit by a blackout. RIM, which owns BlackBerry, said in a statement: "We are currently experiencing a BlackBerry service issue impacting some users in Europe, Middle East and Africa.
"All relevant support teams are working to resolve the issue. We apologise to any customers who may be affected."
A company spokesperson said the firm was unsure of the types of problems UK customers are facing, and whether the disruption is reminiscent of the one in October last year, which saw scores of users across the globe being cut off for up to three days.
It's the latest in a series of bad news for the firm, which saw its shares fall to a nine-year low in June and its new mobile OS, BlackBerry 10, suffer from delays, meaning they'll be missing out on the Christmas market, the most lucrative time of the year.
The firm was also recently forced to make 5,000 job cuts. We're yet to hear more on the situation but will update this post as and when we do.
