Dropbox, the hugely popular file-sync-store-and-share service, went down Thursday afternoon and remains down more than three hours later. Data synchronization from the website and dekstop application are affected, according to the @Dropbox Twitter feed which also assured customers that their data, while not accessible, remained safe.
Creating/joining shared folders, and creating shareable links to files, also affected. We appreciate you patience as we resolve this issue.

Since Dropbox runs on Amazon(s amzn) S3 storage, the snafu sparked concerns about Amazon as well, although Amazon Web Services status page reports no problems.
It’s been a tough week for free cloud services. Microsoft Hotmail and Outlook.com email was down for many customers starting Monday.
