Do the IP Addresses for our instances change when our instnaces are moved across data centers?

Hi Bernardine,

While I'm not 100% certain, I'm fairly confident that the answer is yes, you get a different IP number when your instance moves between data centers. That's how most data centers I've worked with operate.

Bernardine,

Yes the IP address used to access your instance as well as the IPs that your instance will use to talk back to you will definitely change when you move datacenters.   You can find your current IP addresses here:   Service Catalog > Instance Management > My IP Information.   Unfortunately it doesn't appear that we have a function builtin that would tell you the IP addresses used by the paired datacenter for your instance, you can however create an INT for us to provide that information.

Thanks,

You can find a little more information by going to System Diagnostics> Stats. The first few lines have some interesting information. From here I can see this instance appears to be in a San Jose data center (SJC is the airport code nearest the data center.)

That info there is the private IP space used by the server the instance is running on, it's not helpful for users as that IP is only routable within ServiceNow's network and thus isn't reachable by customers.
