eMDR System Status
Update: April 10, 2026
As of April 14, 2025, the ESG NextGen Unified Submission Portal (USP) replaced the legacy WebTrader user interface. This user-friendly web-based platform provides the ability to submit regulatory information to the FDA and track the status through Center receipt.
The production and pre-production eMDR systems experience weekly downtime for maintenance and other scheduled activities. The Electronic Submissions Gateway Next Generation (ESG NextGen) also experiences downtime for these activities, even when eMDR is operating normally. Maintenance (whether scheduled or unscheduled) should take place over the weekend. For this reason, reporters are asked to submit their reports between the hours of 10:00 AM Monday and 5:00 PM Friday (New York timezone, GMT -5).
Scheduled Maintenance
The chart below lists all scheduled maintenance activities for the CDRH data center. Downtime may occur on weekends not listed below due to unscheduled maintenance or ESG downtime.
