Recently, we've been seeing a number of reports in Blogger Help Forum: Something Is Broken , from people suddenly unable to login to Blogger and maintain or publish their blogs. It appears that more and more private network owners are converting their email and office applications suites, to use Google Apps / Docs. This gives the various employers and schools the ability to block people, using their email, from also using extraneous / unnecessary services like Blogger and YouTube - and encourages the employees and students to spend their time more productively. People with Blogger accounts, that are based on the converted email domains, are seeing problems accessing their blogs.
