I have Ubuntu 11.04 installed on my computer. The other day I learned about Ubuntu One and signed up for the service. I placed a couple of files into my Ubuntu One folder and they were loaded to the web (which I logged into and saw). I then created a folder, placed a couple of files into it and marked the folder to sychronize with Ubuntu One. This worked as well.
However, as of last night the syncing has stopped working. I have placed a couple of new files into the folder and I periodically get a small window at the top right of my screen saying that the file x is being uploaded to my personal cloud. The message eventually goes away, but the file is never actually uploaded. So, it did initially seem to work but isn't now. Last night I thought I saw a message on the Ubuntu One website saying that the system was down for maintenance - I can't find that message again today.
The only other thing that happened last night was that at one point I received a popup window asking me to supply login information for Amazon S3. Although it didn't seem right, I put my Ubuntu One user ID and password into this window and told it to remember it.
Any suggestions greatly appreciated. Thanks.
