Planned Archive Downtimes

These are scheduled downtimes which will affect access to the MAST HST Archive. Note: Due to the nature of the archive systems, we cannot always report unscheduled downtimes.

The DADS system serves data from the HST and FUSE archives.


Public HST data is also available at CADC and ESAC:

Staging Disk Capacity

Here is the current capacity of the Archive host's (archive.stsci.edu) staging disk:


Wed Apr 02 00:24:15 UTC 2025

455.0 GB of 8063.3 GB used (5.6%)

If the capacity is near 100%, then the staging disk is full, and HOST retrievals and retrivals submitted through the Web interface will fail. When that happens, you may either

Wait until there is more space on the staging disk (every day, files older than three days are swept from the staging disk), or
you can select NET retrieval instead of HOST and have the data sent directly to your machine.

When the disk is full, and you have data on it you don't need, please let us know so we can delete it to make space for other retrievals.
