@data-eng, @data-analytics-team, @site-infra, @sre:
I'm moving monomp0[1-4] onto new servers and into new dedicated security group mp-mongod-ec2.
Cluster information and network access requirements have been gathered from data-engineering team and summarized in:
I will start moving hosts one by one, starting with hidden secondary, then secondary nodes, then primary.
Despite our best efforts, some connectivity might be lost. Please keep an eye on mp* applications and analytics applications and let us know here if something is broken.
List additional requirements in the comments of pages above and ping @site-infra on #site-infra-channel.
