Maintenance Schedule
NLAD maintenance takes place on a regular basis.
- New versions of the system are deployed to make system changes and upgrades. This usually does not require NLAD to be taken offline.
- NLAD is taken offline for scheduled system maintenance, typically completed on the third or fourth Saturday of each month.
The table below outlines the dates for 2021 NLAD maintenance.
To find out if NLAD will be down during the maintenance, refer to the “System outage?” column to find out if “Yes,” the system will be down and the time during which the system will be down.
