Redunant ISPs how to configure
Ok, we have a T1 and an ISDN.
We are running our own DNS servers and hosting mail and web. However, recently our T1 ISP had some problems and we were down for two days.
How can I plan for this and make an easy transition to the ISDN line and get back up and running ?
The problem I see is the IP addresses are different for the two different lines. So even if I re-configure the Firewall to use the new IP addresses, how do I re-populate the DNS quickly so we are not down for 24hrs or more.
Since we are using our own name servers and I can go to my domain registration and changes the name servers any time. How long do these changes take. I am not talking domain changes just Name server changes.
I was thinking if I have a name server up on the ISDN line all the time I could just go to my domain registar and change the name server and then any request made from the internet would be re-routed to the correct IP address.
Am I going about this the right way ? Any help would be appreciated.
Thanks
