However, none of these links provide access currently. A message "You don't have permission to access /mapss/ on this server", appears when any of the above links is used.
How can we now access these portals (MAPSS or AEROSTAT)?
AEROSTAT has been discontinued and is no longer available.
MAPSS had been discontinued as well, but there were several requests from users to reactivate it, which we have been undertaking in recent months. This process is nearly completed and requires final steps to be made operational again. We will announce on our Web site and here when MAPSS is publically available.
