I am trying to confirm if there will be a EMAIL / WEBSITE outage due to making changes to DNS provider / changing WHOIS tech contact or any other unforseen changes
- website domain is xyz.com DNS managed by MNSI.NET and currently hosted by go daddy
- Email domain is also xyz.com hosted by office 365 and emails MX record hit barracuda email security cloud service first
- We are launching a new website no longer going to be hosted by go daddy and DNS hosted by a different provider other than MNSI.NET
What can cause a outage to EMAIL and or website with what we are going?
