He said that the Tier1 DNS providers force an extended TTL to save traffic and cycles on their DNS servers. Therefore no matter what you set your TTL to some folks will not be able to get to your backup site for an extended period of time. Has anyone experienced this? I am looking to do this anyway in the near future as we are going to switch ISPs soon and I want to ease the pain of re-numbering.
Not sure I understand this. Are you (or your DNS guy) saying that Tier1 DNS providers can override my TTL settings somehow? And what's a Tier1 DNS provider anyway? -- Keith Hunt 330.972.7968 keith () uakron edu Internet & Server Systems The University of Akron
