We are experiencing CDN issues that are impacting u/l and d/l of assets. You may see issues when uploading assets to your Topspin account, particularly with .zip files. As a result customers may experience issues when downloading products as well. Our engineers are totally focused on a fix. More updates soon.
UPDATE [2011-09-06 2:11PM PST]: Our engineers have stabilized things to the point that the only issue customers (fans) may see is slower downloads. If you experience any issues, please file a support ticket. Our engineers continue to work on the issue.
