Error "999" when viewing or burning a new feed

Publishers with Google-hosted feeds based on Yahoo! Pipes or Delicious feed content may see an "Error 999" reported when they attempt to view their feeds, or burn new feeds based on content from these sources. We are working with Yahoo! to resolve this issue, but a full resolution is not expected for several days.

This post will be updated once Google-hosted FeedBurner feeds work properly with Pipes and Delicious-based content.

UPDATE (30-Jan): Delicious feeds work properly with feeds hosted by Google again. Feeds using Yahoo! Pipes as their source are not yet working in the Google-hosted environment. We will post a new, separate update once access to Pipes source content has been restored.
