While git.a.o is not back up and running, we do have a work around in place. Feel free to submit a JIRA ticket about your project for more information.

More information can be found here https://blogs.apache.org/infra/entry/subversion-to-git-service-git

Due to an issue at our vendor's datacenter, git.a.o was taken offline. Data drives were lost during the outage and we're evaluating how we want to rebuild this service. Git repos were all previously moved to gitbox.apache.org and are unaffected by this outage. The only service left using git.a.o was SVN mirroring to github. If you have further questions, please contact Infra via Slack or users@infra.apache.org
