I would like to bring up the load on a new server slowly over time.
Unfortunately there is no front-end load balancer we can use to adjust this, so I just insert a new DNS record for the domain name. This will split the traffic approximately 50/50 between the old and new servers.
My question is, can I adjust the ratio between the old and new server by entering multiple identical records?
example.com. 300 IN A OLD_IP example.com. 300 IN A OLD_IP example.com. 300 IN A NEW_IP
I would hope the above example splits the load 1/3 and 2/3 between the new and old servers.
