When we originally announced that we were shutting down FTP publishing on Blogger, one of the common complaints we heard was that March 26 was too soon. Many of you asked for more time to manage the transition off of FTP publishing, either to migrate your blog(s) to Blogger hosting or to another platform.
March 26 was not an arbitrary date — it was related to an upcoming infrastructure change being made at Google that will render our current FTP code unworkable. We relayed your feedback to the infrastructure team, and they have agreed to postpone their change, which allows us to extend the deadline to May 1.
We are finishing up the FTP migration tool, and are still working to have it out the week of February 22.
Finally, we've done a sweep through your recent comments, and will be updating the FAQ later today with more answers.
