    Nexus answers with Error 503 Service Unavailable when for example the sources-jar of an artifact is requested (but not found) by a proxy repository on an other nexus. Said proxy Repository will be auto-blocked unnecessarily because it believes the service is unavailable (see below). Should the answer not be 404 NOT FOUND, so that the proxy can distinguish between an unavailable service and an unavailable artifact. ---------------------------------------------------------------------- Mail sent by Nexus whose proxy was blocked: ---------------------------------------------------------------------- Howdy, the proxy mode of repository "jboss-public" (repoId=jboss-public, remoteUrl=http://repository.jboss.org/nexus/content/groups/public/) was set to Blocked (automatically by Nexus). Next attempt to check remote peer health will occur in 13 minutes 20 seconds. The previous state was Allow. Last detected transport error was: org.sonatype.nexus.proxy.RemoteStorageException: The method execution returned result code 503 (expected 200).
