Switching ISP & IP addresses. How to minimize downtime for public access to our web resources?
Posted on 2011-04-27
How do small-mid sized companies switch ISPs, which will include changing static IP blocks, and minimize downtime for public access to our web resources? We host some of our clients websites. We can't be off-line for nn hours.
Via GoDaddy (and others) , we have all the A records pointing to our IIS Server's public IP address.
When we make the ISP SWITCH, I know we can go to the Domain manager on GoDaddy and repoint the A records, but won't that be like up to a 24 hour delay? That's too long, our clients will be screaming.
There's got to a be standard way to do this.
Any how-to comments are appreciated, 500 points.
