The Federal Communications Commission’s business has closed due to the government shutdown.
The FCC has released its statement of operations [pdf] in the event of continued shutdown. CORES and emergency systems will remain online. However, the Commission has made no formal commitment to keep the Public Inspection File system online during the shutdown.
Once the FCC shutdown begins, you will have until the second day of normal operations to upload files as required by associated deadlines.
You can visit NFCB’s website and REC’s shutdown page for updates.
