Whalewisdom was unable to release new filings from around 3:30PM EST to around 7:30PM EST on Thursday due to a huge surge in 13D/G filings that had to be processed.  There were 3,850 Schedule 13D or 13G filings (mostly 13G’s) released with 2,583 of them having an event date of December 31st, 2012.  It was too much for the parser to process in a timely manner so I’ll have to adjust for next quarter.  There was also a caching glitch on Friday morning that caused the site to go down for a few minutes, but that has been corrected now.
