1) Message boards : Number crunching : How do we (Message 16922) Posted 19 May 2007 by maurice Post: really glad to hear that things are going. I don't expect that the physical movement of the webserver should cause much trouble. I'd expect the only difference we should see is a different IP Address. How do you plan to do that switching. I expect they will finally update the master DNS server to point to a CNAME for the new server (IP). Of course the propagation will take some time. Will the current webserver be shut down during that time or will you switch them more transparently? To clear all DNS caches on linux you have to resart your name service caching daemon (nscd) and your local dns server (if you don't use the nameservers of your ISP). If you do use the nameservers of you ISP, it may take a while till they will update their records. From what I see from the cern soa record, it should not take more than 20 minutes (if you clear the local cachings). Maurice
