Enhancements to Maven Central
Sonatype is committed to ensuring that Maven Central is a reliable resource for the community. We are continuing to invest in enhancements that improve system availability, including the conversion to virtual systems and adding redundancy to Central’s Internet connection. These new improvements follow the deployment of the new official Maven Central repositories in the UK that enabled much faster access for all Maven users in Europe, as well as providing another geographically redundant backup of artifacts.
Virtual Servers: We now have 6 nodes running in a private cloud cluster and both Central machines in the US are fully converted to virtual machines. This will allow the two systems to be completely isolated from hardware failure and provides greater flexibility for load balancing and performance tuning.
Internet Redundancy: Maven Central is now connected to Contegix’s fully managed network which provides multiple routes to the Internet. While the existing connection had been extremely stable in the past, we believe that using the managed and redundant network is the best choice for providing a reliable service to our users. The conversion to the new network is already completed and you may notice that Maven Central now has a new IP address.
We are aware that some users have firewall rules that are locked to the external service IP. Because of this, we strive to maintain a consistent IP for each system, however the primary mechanism for accessing the repository is by DNS for most users. At times, our failover escalation or maintenance procedures may require us to redirect the DNS for one system to another. For this reason, if you have firewall rules in place that need specific IPs, please allow this list so that you won’t be affected by any temporary transitions:
- 207.223.240.88 : US primary
- 207.223.240.92 : US staging / standby
- 89.167.251.252: UK Primary
- 89.167.251.253: UK standby
New Service to Search for Artifacts in Maven Central
Sonatype is pleased to announce the availability of http://mavencentral.sonatype.com, a new website for searching the artifacts in the Maven Central Repository.
What makes this new service different from other sites that index and search the central repository? The new search service is not just a place for quickly and easily researching artifacts on which your project depends, but it is also the most up-to-date source of information on those artifacts other than browsing repo1.maven.org directly.

Now Available: Central download statistics for OSS projects
Maven Central contains over 260,000 artifacts and serves over 70 million downloads every week. It has become the principal resource for exchanging Java artifacts with demand doubling year over year. Getting artifacts into Central is the most effective way to get your software to developers since every build tool that can download Java libraries knows where to look for a world of libraries and dependencies, and that single, authoritative place is Maven Central.
Earlier this year, we announced the availability of official repositories in the UK to improve performance for the users in Europe. Today we are making the artifact download statistics available to the projects whose artifacts are served by Central. This has been one of the most frequently requested features by project teams. Since the raw Central logs are larger than seven gigabytes every day, processing this data is no small undertaking.
The statistics are available to all projects hosted using Nexus at http://oss.sonatype.org, http://repository.apache.org and http://nexus.codehaus.org. These three avenues represent the majority of projects actively contributing artifacts. Nexus’ security mechanism already in place on these instances provides a mapping of repository path to project which allowed us to easily roll up the counts for each team.

Benefits of a Repository Manager: Part V External Partners and Vendors
In the previous posts in this series, we’ve talked about how a repository manger changes the development cycle. In this post, I’m going to talk about how a repository manager can be used as a way to interact with third parties. Specifically, I’m going to talk about vendors and partners.
