Today was to be the day for Google to finally roll-out the expected redesign of Blogger, but it seems things haven’t gone as planned.

Late last night, the Blogger Twitter account announced that “scheduled maintenance” was underway and later said that it was “sorting out a few issues,” but now, hours later, the service still appears to be out of commission.

We would link to posts about the redesign, which the company announced nearly a month ago, but alas, they are all on Blogger itself. The cache of the announcement gives a preview of what The Next Web reported earlier today that Google was rolling out to its users.

The latest report from the Blogger Twitter follows:

We are very sorry that users are unable to publish to Blogger right now. We have rolled back the maintenance release from last night and as a result, posts and comments from all users made after 7:37 am PDT on May 11, 2011 have been removed. Again, we apologize that this happened and our engineers are working hard to return Blogger to normal and restore your posts and comments. We will post a report once this work is complete.

The company first debuted its redesign at this year’s SXSW, at which point it had more than a half a billion blog posts.

Update: Despite tweets about the redesign and a story on The Next Web, Blogger has said that it was “not rolling out the new UI, but instead conducting a routine maintenance.”

We’ve contacted Google for more information but haven’t heard back yet.
