Failover

"Dear BlackBerry user, as a 9 hour power down will take place in Hong Kong this weekend, we will failover the BlackBerry service to the Singapore environment. Unfortunately, we are unable to maintain a service whilst the maintenance is carried out due to the nature of the maintenance." My italics, obviously.

At first I thought 'failover' was a madeup word, or an error. But if you look on Wikipedia it's there (which doesn't make it real, I know. But it's start.)

But if you look the definition of 'failover' it implies that service is maintained through the primary outage. This doesn't appear to be the case on this Blackberry failover. It raises the awful possibility that I may not be able to send or receive text massages for part of the weekend. That's a disaster!
