Post published but does not display

I published a post last night at this URL: https://markkelly.wordpress.com/2013/02/24/psst-hey-buddy-drink-this-in

It publicized into Twitter with this shortened link: https://wp.me/p2dmj-Hv

WP did not, however, continue on and display the published post on my home page. It did not appear when I followed the links.

Did WP have a systemwide problem last night? Is there any prospect of recovering the post? I wrote it in WP and don’t have a backup. There is no sign of it on my dashboard, either as a draft or as a published post.

Would be grateful for any help possible.
