Don't you forfeit too much control this way? For example, the load on your servers would be determined by the caching behaviors of all the various DNS servers and clients out there. I think this scheme should only be used as a front line that leads to another layer of load balancers.
- DenisM 18y agoThe idea is that there is enough chaos in the Internet to produce practically random result with sufficiently large number of users. Random is pretty good, unless you must proactively shift load to least-loaded systems (in which case you have to be super careful to avoid oscillations) . One drawback is that you can't take system out of rotation as quickly, but this can be somewhat mitigated by setting very low TTL (60 seconds).
