This happened during the shutdown..
The USGS did not report any data during that period...at all...
Somebody gave a link to http://earthquake-report.com/2013/10/08/moderate-earthquake-off-east-coast-of-united-states-on-october-8-2013-2/ where the Oct 8 quake was reported, but one of the sources that website cites is the USGS. So though the USGS website was probably down and they weren’t reporting anything during the shutdown, it was just for show and they were still taking down data, which was added to this other website once the shutdown was over.
