Why did I receive an "Error: Inventory request failure" message during a download request from The National Map?

The "Error: Inventory request failure" message occurs if our ScienceBase catalog database is not responding to download requests. To ensure data integrity, the ScienceBase catalog is shut down for nightly backup at 11:00 pm Mountain time, which takes 1-2 hours. If you find that the message is still occurring even after the allotted two hours, please contact The National Map Service Desk at to alert support personnel that there is a problem with the ScienceBase catalog.
