Update 1
Burnout Paradise Server Fixes - 04/03/08

In today's server upgrade we've deployed fixes to the Xbox360 account verification. It was found that a very small number of Gamer Tags were unable to connect to the Burnout Paradise Servers and would receive the message "The Burnout Paradise servers are not available at this time". This would only occur to Gamer Tags that had been previously owned by somebody else and had been renamed before the current owner registered them.
Today's server deploy @ 10:00GMT resolves this issue.

Update 2
Burnout Paradise Server Update - 11/03/08

During Tuesday's server maintenance (11/03/08) we will be making fixes to the ranking system. Following feedback from the community, we have found that players can loose a large amount of ranking points through no fault of their own. We will be addressing this with a server side fix.

Thanks

The Burnout Team.
