Federal Communications Commission "FCC/DA XX-XXX" DA-22-348 Released: April 1, 2022 FCC’s ELECTRONIC COMMENT FILING SYSTEM TO BE UNAVAILABLE DURING THE WEEKEND OF APRIL 2-3, 2022, TO ACCOMMODATE SYSTEM UPGRADE  The Federal Communications Commission will be performing system improvements to the Electronic Comment Filing System (ECFS) beginning at 12:00 a.m. EST on Saturday, April 2, 2022, and continuing through that weekend.  The system upgrade is expected to be completed and full service restored to the public no later than 7:00 a.m. EST on Monday, April 4, 2022.  The upgrade will enable immediate system improvements and allow for expanded features and functions to be introduced into ECFS in the future.  During the time that the upgrade is being performed, ECFS will be unavailable to the public for all purposes, including for filing, searching, and retrieval of documents.  Parties who may need to reference documents in ECFS during the period of inaccessibility are therefore advised to download those documents no later than 11:59 p.m. on Friday, April 1.  Access to other Commission systems and databases will not be affected.  Because the period of inaccessibility will occur entirely outside of normal business hours, filing deadlines will not routinely be extended.  Requests for extension of time due to particular circumstances will be considered consistent with the Commission’s normal procedures.  Additionally, the current Application Programming Interface (API) for submitting filings to ECFS will no longer be available; to submit a filing, use the web interface at https://www.fcc.gov/ecfs/filings.  The API for search and retrieval will remain available; see https://www.fcc.gov/ecfs/help/public_api for instructions.
