As a few users have noticed (thanks for the emails!), the MyExperience website is currently down. I am working with SourceForge to resolve this problem. It looks like it may have something to do with their recent data center migration on 09/30. In the meantime, you can still visit the MyExperience Wiki and download the MyExperience tool here.
Update 2008/10/03 10:30AM: You can follow the status of this issue through a support request on the SourceForge website here. So far, the support team has not been too helpful. Unfortunately, this is not the first time I have experienced problems with SourceForge with critical services that should be more reliable. I realize SourceForge is a free service and I do put that into perspective. However, I have contemplated switching over to other open source hosts like code.google.com but this would be time consuming and effortful so I would prefer otherwise.
Update 2008/10/03 01:17PM: Fixed! There was an issue with index.php taking priority over index.html on the webserver. This problem never cropped up in the past and was a result of the transition to the new data centers on SourceForge.
