ZCTAs in the Data Profile tables

Hi,  Does anyone have any information about the availability of ZCTAs on the new census.data.gov site?  I am a former Factfinder user and am not an ACS expert but did learn through the videos how to go to the Data Profile pages, select the ZCTA geographies we need, and copy the table with headers to place in our Excel spreadsheet.  

Last Friday the webpage stopped working and will not bring up the ZCTAs at all.  Are they just working on them as a part of the transition or is there another reason?  or work around.  

Thank you for your assistance.
