We have had a catastrophic hardware failure on opennms.org, opennms.com, and related sites. We are in the process of getting new hardware and preparing restores. Sorry for the inconvenience.
Source code, as always, is available on SourceForge, as well as the latest RPM packages (albeit without handy yum dependencies).
