But luckily, the problem was resolved within a few hours. Whatever the problem was...who knows?
Here is a response Ann Althouse received from Google when her blog was deleted about a year ago:
Here’s what happened: during scheduled maintenance work Wednesday night, we experienced some data corruption that impacted Blogger’s behavior. Since then, bloggers and readers may have experienced a variety of anomalies including intermittent outages, disappearing posts, and arriving at unintended blogs or error pages. A small subset of Blogger users (we estimate 0.16%) may have encountered additional problems specific to their accounts.
So could be that happened to me overnight. Welcome back, viewers.
