WordPress.com had some server issues earlier today, which made it impossible to post or even draft posts for some time.
As a result, everyone participating in Post A Day can take a deep breath. Simply do a make-up post tomorrow, or if it’s not too late now, get your post up today.
Sorry for the inconvenience. If you want details on what happened, or to get real time updates on WordPress.com status, follow @wordpressdotcom on twitter, or make sure to follow @postaday, as we try to retweet their updates.
