BlackBerry's chief executive Thorsten Heins apologised today to customers who had suffered disruption.
He said in a statement:
I want to apologise 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% of our user base may have been impacted.
Preliminary analysis suggests that those customers may have experienced a maximum delay of three 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 apologise to those customers who were impacted today.
