Switching from the Old Network to the New¶
We have two address ranges that come in on a single redundant link, so we're exchanging that redundant link for two separate links, each taking responsibility for an address range (136.26.15.0/24 and 136.206.16.0/24). So we're surrendering redundancy to gain uptime/connectivity during the switchover only. Once the new servers are production ready, we can recombine the link to regain the redundancy.
