Various synchronization issues between oss.sonatype.org and Maven Central

When using oss.sonatype.org to publish my open source projects to Maven Central, I notice various synchronization issues:

• Most importantly, it's now more than twelve hours ago since I've release various modules for TrueZIP 7.0 to oss.sonatype.org. None of them has shown up on Maven Central so far at http://search.maven.org.
• In general, there used to be a lag between Maven Central and this Search site. Now I can't verify this anymore because I get redirected to this search site.
• When I search oss.sonatype.org for "truezip" and look at the artifact information of the search results, then only the module truezip:7.0-rc1 seems to be "Contained in Repositories: Maven Central, Releases", but that's not true. All 7.0-rc2 components are on Maven Central, too, but not according to this search result.

In general, the information on http://oss.sonatype.org, http://search.maven.org and http://repo1.maven.org/maven2/ seem to be completely out of sync at least for the TrueZIP project.

Please help, I need to get my 7.0 release published.
