We have on site servers. These communicate with outside devices continuously updating data in real time.
The traffic coming in to the servers is blocked during failover as it is being pushed in. During failover, there is a different IP, and so the information doesn't come in (inbound rules no longer apply as it's in failover).
So what I would like to do is find a way to get that information if needed.
If there is a 5 minute failover, it's not a big deal. But if we establish it's going to be in failover for a substantial period (4 hours +) it would be good to find a way to get that data in somehow.
