[bitfolk] Some feedback about IP renumbering needed

Hello, We're now very close to the point when we need to begin getting you all to renumber your IP addresses. We are not there yet, but here is some more info: https://tools.bitfolk.com/wiki/Renumbering_out_of_212.13.194.0/23 Before finalising the procedure and sending out instructions I could use some feedback from you on a couple of points. These involve situations where BitFolk is contacting you by IP address. - BitFolk Backups Our backup servers are doing rsync-over-SSH by IP address. If we change the IP addresses our side then your backups stop working until you make your change. If we don't change the IP addresses our side then your backups will break when you make your change, and then you would need to contact support to get the change done. Which would be preferred? - Nagios checks Many of you have Nagios checks. These are done by IP address. If we immediately make the change on our side then alerts will start to fire for you, and will not right themselves until you complete the IP address change on your side. If we don't make the change on our side then as soon as you make your change, alerts will start to fire and then you'd have to contact support to ask for the monitoring to be fixed. I have a strong preference for us making the change as soon as you have the info to make the change your side, so that the monitoring fixes itself as you do the work. Any other ideas how to do it? - Old rsync-style zone transfers Some of you still have DNS secondary services driven by zone files that we are rsyncing from you. This is happening by IP address. This service was deprecated years ago, since everyone got enough RAM to run a proper DNS server for this purpose. I would like to finally retire this service. How much time would people like to stop relying on it and switch to running a real DNS server? - DNS slaves Those of you who have secondary DNS services will be running your own DNS server on your VPS and we'll be doing AXFR to that IP address. The DNS secondary service comes with Nagios monitoring, so as soon as we switch the IP configured on our side then monitoring as mentioned above will begin to alert. There can be multiple masters, so what we could do is set both old and new IP addresses so that zone transfers can continue to take place, but our monitoring can only have one IP address. With that in mind I think I would prefer to set both old and new IPs as masters, let monitoring alert for your TCP/53 and that will fix itself as your sort out your new IP address. Any other ideas how to do it? As far as possible in all cases above I would like to avoid the situation where we have to chase individual customers one-on-one about things that suddenly stopped working. I can imagine this might not be avoidable—particularly in the case of the backups—so if we have to do it, we have to do it.
