Barthelmy (NASA/GSFC), N. Gehrels (NASA/GSFC), F. E. Marshall (NASA/GSFC) on behalf of GCN announce: A lapse in appropriations of the US Federal government may significantly impact the operation of the GCN. We are uncertain regarding the scope of the impact, but network access to NASA GSFC systems where GCN is hosted may be cut off from the general public. This may lead to the possibility of being unable to accept or distribute Notices and Circulars. The GCN web site (gcn.gsfc.nasa.gov) may also be unavailable. The impacts could start as early as 00:01 UT October 1.
