I am trying to install Atlassian Connector for JIRA, but installation hangs forever. Atlassian's wiki says that this could be caused by Mylyn Extras not being available. Indeed, if I try to browse it through Eclipse update tool it complains that http://download.eclipse.org/tools/mylyn/update/extras can't be reached. Is the site really down or is this a bug with the update tool? (eg. wrong URL)
