"Some blogs are seeing a new post that says 'eeyore isFrom Known Issues for Blogger, which tracks issues for the Blogger service (the one that provides the service for this site).
"We are identifying the cause of the problem and are working on a fix."
Update: The plot has thickened:
"Update: During routine testing, a bug caused a small number of FTP blogs to publish a test post. No systems or accounts were hacked. We have corrected the original bug, and are working to remove the test data from the blogs. In the meantime, republishing your FTP blog will also correct the problem. We apologize to those bloggers who were affected - we are looking at mechanisms to prevent similar occurrences in the future.So is this the "eeyore" bug? It must be a sad bug. I still think it must have been a joke.
"Note: Some users with non-FTP blogs who have opted to receive post confirmation emails may have seen a spurious email about a test "eeyore is cute!" post. This email can safely be ignored.
"Update: This is now fixed."
