Website / Email outage - -If so How long?
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
What can cause a outage to EMAIL and or website with what we are going?
- 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?

Changing DNS contacts should never cause any kind of outage.
No, but not updating relevant IP changes in your DNS record sure will
Did you verify the IP information in your DNS was updated properly to reflect the service changes?
DNS - New host/provider
DOMAIN - New host
Mail Servers - If you changed these too
There's no such thing as a website for outage as far as I concern, You need to have skills to determine if a site went down. The issues vary, for example.
1- DDOS attack.
2- Cluster Down.
3- DNS forwarding issues.
4- TDL issues (that never happens but no bad to put it here)
5- Routing issues (load balancing, DNS round robbing, bad cache.
Again, the issue varies.
Something you can do is look for that particular website, see if you can telnet to it, try to ping it. Do a Nslookup find the name server that belongs to, see if the registrar is having issues, give them a call. Again, the problem might vary.
