  • Notice:

    In an effort to streamline system maintenance, AIR will be taking all online systems offline once per month.  This will allow AIR to systematically roll out updates. Additional updates that won’t cause disruption to live systems may still occur outside of the maintenance window.

    The next scheduled maintenance window will be from 6 p.m. on Friday, September 29 until 11 p.m. on Sunday, October 1.  The DeSSA portal and all systems accessed through the DeSSA portal will be offline during this window.
