Family Tree DNA's plans to shut down both YSearch and MitoSearch were announced in the FTDNA Forums by Darren on the 10th. While both sites have needed updating for a long time, they have provided a valuable service to the community. It is my hope that some part of the community will come together to build new independent sites.
I wanted to let you know that it looks like Ysearch and Mitosearch are finally going to be shut down. Management is aiming for the end of this month but the exact date has not been announced yet. I would recommend getting whatever data you may want off of it as soon as possible.

Update: FTDNA sent out an email about the closing of the two sites.
