Stephen Bates, the UK managing director of Canadian mobile phone maker Research In Motion has publicly apologised for the network outages that resulted in millions of users across Europe and the Middle East losing their BBM messaging service and BlackBerry Internet Server (BIS) for more than two days.
Speaking at the beginning of his keynote at London's third BlackBerry Innovation Forum, Bates said that Research In Motion is "working hard around the clock to resolve the issue", admitting the outages were "not acceptable".
Although he didn't go into any detail as the problem's cause - said to be a faulty switch at the company's Slough headquarters - Bates said RIM's executive team were "working on this night and day", and that they were "not going to stop until they get to the end of the problem".
Bates went on to reassure consumers that RIM would "continue dialogue through carrier partners", where they are "doing their best to improve communications, with updates on Twitter and Facebook".
Over 70 million people use BlackBerry smartphones worldwide, with 20 petabytes of data going through the company's network every day - some seven million of those handset owners are based in the UK.
