I can't rule out technical explanations (like unannounced maintenance issues). But there have been a variety of anomalies, e.g.,
- occasional failure of blog search to retrieve a recent post by a salient keyword in the post
- one of my most popular posts, with daily readers for weeks, hasn't attracted a reader for months
- blog readers (including my mom) report occasional problems trying to access the blog
- there have been extended uncharacteristically long periods when no readers have accessed the blog, including the last 2 days.
There are some allegations of Blogger having taken down certain political blogs. I don't know if political opponents are making frivolous complaints to prevent other readers from exercising their constitutional rights in reading my opinions, but if this nonsense continues, I may migrate the blog to a personal website, alternative service or conservative website.
