NEW ELECTRONIC COMMENT FILING SYSTEM SCHEDULED TO LAUNCH ON 
JUNE 20, 2016, FOLLOWING WEEKEND OF DOWNTIME DURING UPGRADE
The Federal Communications Commission will transition to its new Electronic Comment Filing 
System (“ECFS”) system on the morning of Monday, June 20, 2016. This will be a “hard 
launch,” meaning that the legacy system will no longer be available after the transition. All 
documents in the legacy system will be accessible in the new system, and saved links 
(bookmarks or favorites) to documents and proceedings should not need to be adjusted.  This 
modernization project is expected to significantly improve the resiliency and performance of 
ECFS.  
The Commission will continue to take feedback and improve the system leading up to and 
following this transition. As part of this process, the Commission has scheduled a number of 
public, web-based tutorials to provide multiple opportunities for users to become comfortable 
with the new system.  All demos will be listed here: https://www.fcc.gov/news-events/events. As 
of this date, tutorials have been scheduled for June 7, 9, 14, and 16. 
In order to best ensure that this important public-engagement system is fully functional during 
regular business hours, the Commission will take down the legacy ECFS application starting at 
11:59 p.m. ET on Friday, June 17, 2016, and the system will be unavailable through the 
weekend. The Commission plans for the new system to be available and fully operational by 8 
a.m. ET on Monday, June 20, 2016.  The old ECFS system will not be available once the new 
one is operational, but all files will be accessible in the new system. Should any unforeseen
delays take place, the Commission will release a Public Notice on the front page of its website, 
FCC.gov, informing users of any impacts.
Given that ECFS is expected to be fully operational during all FCC business hours, the agency 
does not plan any changes to any deadlines.
