Seems that
Viking Pundit and
Betsy's Page (who suffered the same fate recently) are in good company. Here's the embarrassing admission at the newly restored
googleblog.blogspot.com:
The Google Blog was unavailable for a short time tonight. We quickly learned from our initial investigation that there was no systemwide vulnerability for Blogger. We'll let you know more about what did happen once we finish looking into it.
Update: We've determined the cause of tonight's outage. The blog was mistakenly deleted by us (d'oh!) which allowed the blog address to be temporarily claimed by another user. This was not a hack, and nobody guessed our password. Our bad.
Bad indeed and the laughs are echoing around the Internet. You'll see that they aren't exactly admitting that the spam filter got it, but there aren't too many reasonable alternatives and that seems to be
the general belief:
Blogger blog?
check
allows trackbacks?
check
exists just for SEO's?
check
nearly all posts contain a link to a site owned by the same people?
check
posts made by non human entities?
check
aha! we have one! Delete it! Delete it!
