A little notification might go a long way.
Referring to this morning, Barry from WordPress posted this last night:
Tomorrow around 9AM Pacific time we will performing some back-end code changes that may result in a few spots of weirdness for things relating to categories. This includes categorizing posts and links. The maintenance should only take a few minutes but I have allocated a couple hours just in case. Once the maintenance is complete you should see new functionality in your admin area so keep your eyes peeled. I will update this thread once the maintenance is complete.
Just so y’know.
(What the hell do you mean, “we’re out of coffee?” It’s not even 7 AM, I’m awake, AND THERE’S NO COFFEE? HOW DOES THIS HAPPEN?????)
