If you or your colleagues need census data during this government data outage, head to http://beta.censusreporter.org/.
They have migrated the ACS 2011 1, 3, and 5 year data and the new ACS 2012 data into their system. The 2011 release is up and running, and they are working on formatting the 2012 data now. You can browse for facts and figures or just easily get at the tables you want to download.
The interface is undergoing some polishing work as they work in the open and gear up for our beta release, but the site is mostly there.
