Problems persist at the popular blog hosting service TypePad, with numerous users reporting that they are unable to access their blog management system. In addition, a number of TypePad users report that posts from the past three days have disappeared from their blogs. While TypePad-hosted sites are visible, service operator Six Apart says the TypePad blogging application is currently unavailable and describes the status of TypePad sites as "degraded." In a subsequent update Six Apart attributed the problems to a disk failure during routine maintenance which forced them to restore blogs from backups that were several days old, which accounts for the missing posts.

TypePad, a hosted version of Six Apart's Movable Type blogging software, has been a major beneficiary of the blogging boom. But that growth has brought challenges, and TypePad has experienced significant performance problems in recent months as its has outgrown its existing space and begun a transition to a new data center. Six Apart has issued a series of apologies for the poor performance, which has drawn complaints from business bloggers using TypePad.

TypePad isn't the only blog-related service being strained by recent growth. The web-based RSS reader Bloglines has also struggled with poor performance in recent months. "We're not going to beat around the bush about this. Bloglines performance has sucked eggs lately," the staff noted in a message to users. "In short, Bloglines has been busting at the seams like the Incredible Hulk. All of us here at Bloglines have been foregoing sleep and social lives over the past several months to keep Bloglines running and preparing for our move to a new access center."
