Yes, my tests and also research/discussion from other threads. I favor the idea of putting the responsibility of failover updates on the cluster side rather than relying on everyone elses servers to update properly. Some of it is based on the assumption that not all DNS servers pay attention to the low TTL on DNS... unfortunate but a reality... also DNS caching affects this. The IP take-over seems like a more reliable approach because of TTL and caching issues. The IP take-over response times seem comparible to the DNS TTL update but again put the update responsiblity on the cluster rather than trusting that the changes will quickly update across all the DNS servers on the Internet. > > > > > > > --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "scalr-discuss" group.
