[OSM-dev] OSM Data Update

Just following up on my own posting. Just just updated anotehr are that 
lacked some ways from the OSM server

• internal database import
• tile generation

This time the end of the A25 in Geesthacht. The motorway ends too early 
on the field and has no conenction to the B5. When I check out this 
area on www.openstreetmap.org the (View pane) it looks just fine!?

Does the maps diplayed on www.openstreetmap.org represent the current 
database contents or some older state (tiles generated every now and 
then)??

I am just trying to learn how save it is to update from the OSM server 
continusly. If ways vanish without warning and without immediate proper 
replacement that would be a great problem for us. Is thi sto be 
expected or should I further look for an error in our software (OSM 
scanner, import)?

Thanks a lot,

   Andreas
