Nelnet services will be unavailable during the maintenance outages, which includes outages for merchants using Nelnet during production patching and system modifications.  The list below are dates for this year.  This list is subject to change without notice.  Treasury makes every effort to email notifications of outages in advance.

There also could be separate (not on list below) Nelnet software updates which could cause outages.  Treasury will forward information of these when Nelnet provides notifications.
