Andrew Bocking, Head of BBM at BlackBerry, has written a post on the Inside BlackBerry Blog which explains the problems that occurred on Saturday's launch date, and what's being done right now to fix them.
"Last week, an unreleased, older version of the BBM for Android app was posted on numerous file sharing sites. We were aware of an issue with this unreleased version of the BBM for Android app. This older version resulted in volumes of data traffic orders of magnitude higher than normal for each active user and impacted the system in abnormal ways. The version we were planning to release on Saturday addressed these issues, however we could not block users of the unreleased version if we went ahead with the launch.
We attempted to address the problems caused by the unreleased version throughout the day on Saturday, but as active users of the unreleased app neared a million – and accelerated – it became clear that the only way to address the issue was to pause the rollout for both Android and iPhone.
The team is now focused on adjusting the system to completely block this unreleased version of the Android app when we go live with the official BBM for Android app. We are also making sure that the system is reinforced to handle this kind of scenario in the future. While this may sound like a simple task – it’s not. This will take some time and I do not anticipate launching this week."
There you have it. BBM will most likely not be available this week on iPhone and Android because of the fixes being implemented. As soon as we have more news, we will definitely share them with you guys as well.
