On the homepage of this project here on SourceForge it says:
Graphite2, a new version of the Graphite engine, is available at: http://projects.palaso.org/projects/graphitedev with its own bug tracker.
Trying to access that URL produces this error, after some delay:
The proxy server received an invalid response from an upstream server.
The proxy server could not handle the request GET /projects/graphitedev.
Reason: Error reading from remote server
