Also see top  of http://wiki.openstreetmap.org/wiki/Bing/Coverage

"Please use this page for recording coverage. Do not use boundary  
relations. Large, detailed relations can be exceptionally slow to retrieve  
and cause very high server load, especially when accessible via an  
OpenLayers slippymap client. Significant problems have already been caused  
by people trying to map coverage with a relation, and then posting the  
relation URL."
