Hi everyone,
we are currently experiencing a problem with our machine hosting Nexus on maven.xwiki.org (or nexus.xwiki.org). The machine is not reachable since 12:00 PM approximately, and our infra team is working on the problem. We don’t know yet how much time it will take to recover it, but we’ll announce it here when we’ll have more information.
Sorry for the inconvenience.
