Last May, we discussed a number of challenges facing Blogger users who relied on FTP to publish their blogs. FTP remains a significant drain on our ability to improve Blogger: only .5% of active blogs are published via FTP � yet the percentage of our engineering resources devoted to supporting FTP vastly exceeds that. On top of this, critical infrastructure that our FTP support relies on at Google will soon become unavailable, which would require that we completely rewrite the code that handles our FTP processing.

Three years ago we launched Custom Domains to give users the simplicity of Blogger, the scalability of Google hosting, and the flexibility of hosting your blog at your own URL. Last years post discussed the advantages of custom domains over FTP and addressed a number of reasons users have continued to use FTP publishing. (If youre interested in reading more about Custom Domains, our Help Center has a good overview of how to use them on your blog.) In evaluating the investment needed to continue supporting FTP, we have decided that we could not justify diverting further engineering resources away from building new features for all users.

For that reason, we are announcing today that we will no longer support FTP publishing in Blogger after March 26, 2010. We realize that this will not necessarily be welcome news for some users, and we are committed to making the transition as seamless as possible. To that end:

• We are building a migration tool that will walk users through a migration from their current URL to a Blogger-managed URL (either a Custom Domain or a Blogspot URL) that will be available to all users the week of February 22. This tool will handle redirecting traffic from the old URL to the new URL, and will handle the vast majority of situations.
• We will be providing a dedicated blog and help documentation to provide as much information as possible to help guide users through the migration off of FTP.
• Blogger team members will also be available to answer questions on the forum, comments on the blog, and in a few scheduled conference calls once the tool is released.

We have a number of big releases planned in 2010. While we recognize that this decision will frustrate some users, we look forward to showing you the many great things on the way. Thanks for using Blogger.
