That and “ALIAS” records.
It’s way less of a problem now than it was 20 years ago (at least in the Western countries I have services in my career) but it has traditionally also been an issue for a hard cutover of services, especially for SMB and even small enterprise businesses doing things like MX cutovers.
- mercora 2y agoFor hard cutovers it might be a viable strategy to forward or redurect traffic inbetween changes. That is, either let the old destination forward to the new, or vice versa, then update the records to the new destination, or have an intermediary forwarding destination where you can change the destination address on an an instant and once settled move the record to that.
