The virtual webservers are configured using puppet using by this file: https://github.com/apache/infrastructure-p6/blob/production/data/nodes/netbeans-vm1.apache.org.yaml (note that this is a private github repository for ASF committers). All ASF committers can pull from the repository, make modifications, push these modifications into a branch of the repository and create PRs from that (the repository can not be forked!). The PRs then need to be merged by a member of the infrastructure team. Depending on the intended change, this can be easier, than explaining the change that is intendend in an issue. TIP: if the PR is related to an issue, it's good practice to start the commit message with "[INFRA-XXX]" or "[NETBEANS-XXX]", where XXX is the issue number.
