Publicize is the feature on WordPress.com that allows you to send your posts to various social networks (Facebook, Twitter, LinkedIn) to let your friends and followers know about your activity on WordPress.com.
We’ll do our best to make this maintenance go smoothly.
If you publish a post during this time, it’s possible the post will not get sent to each of the social network accounts you have connected via Publicize. If you notice such an absent post, please follow these instructions to get the post sent out correctly.
1. Wait a few minutes. Patience is always the first step :)
2. Edit your post. (Go to your blog’s dashboard → Posts → All Posts then put your mouse cursor over the post you want to edit, and click that post’s “Edit” link.)
3. Click the “Update” button.
