Due to resources and low usage, decommissioning of svnmirror.rim.net is being planned. 

There are few enough users that going against the main server at foundry51.qnx.com, won’t cause any issues. To switch 
from svnmirror.rim.net to foundry51.qnx.com, please consider the following commands:
$ svn switch --relocate http://svnmirror.rim.net/svn/deckard-65x/developer/branches/BB10_3_1 http://foundry51.qnx.com/
svn/repos/deckard-65x/developer/branches/BB10_3_1
$ svn update
