Client Post-Migration Notice

  • How do I find where my site is hosted or even pointing to?

  • To perform a WHOIS search click here!

  • WHOIS searches cannot be used with ‘subdomains’

Note: The WHOIS Registrar URL (domain host) is not always accurate due to SSL Transfers, etc... The DNS nameservers given generally will be however.

  • What is the zone file? This is a file containing all of the records regarding your domain (mx,cname,ns,A-record,etc...)

  • Who has control over the zone file for a domain? This depends on certain criteria your domain meets (see below)

  • A-Record (Domain/Subdomain) -

    • What is an A-record? An A-Record is used to point a logical domain name, for example: "", to the IP address of Corecommerce’s hosting server (website), "".

  • In the below example the client needs to update their IP with whoever controls the zone file as we do not control of this from ‘CoreCommerce’.

    • This client uses the subdomain (located in settings>domains)

    • Because of this they cannot directly WHOIS search for but must instead search for

    • This tells us below their nameservers point to ‘’ which is a default GoDaddy nameserver or a NON nameserver.

    • It also more than likely means they are using an A-record to point

    • Their IP must be updated to:

    • Each store will have a specific IP associated depending on server or dedicated IP’s.

  • How do I know if my DNS values are outdated? The below values are the only ones that should currently be in place, any other values are considered to be outdated and may cause unforeseen issues with your store:


  • Why are my emails still not working? Depending on who has control of the zone file determines where email values would need to be updated.

  • Examples include:

    • CoreCommerce hosted emails can be updated directly from within the Store Admin (See KB article)

    • Third Party Emails for example (GoDaddy, Google Apps (gsuite), and Outlook Online) all have various email values associated with them. If the DNS points to CoreCommerce we need the values from those email hosts in order for you to receive emails from your store. These values vary by email host and as such we recommend contacting yours directly to obtain and provide those values to us by emailing them to

    • Example values include:  (mx records, cname, srv, SPF, DKIM,  etc...)

    • If your DNS is not pointing to Corecommerce then we have no control over the zone file regarding emails and how they are delivered.


If you suspect our email server may be blacklisting your email, contact with the email you feel is not working.


I made of all the above changes why is my website still so slow?

  • Pointing to broken or incorrect links within your website such as:

    • Images uploaded to the WYSIWYG editor of any product or page.

    • Hard-code html links such as in your body or header.html/footer.html

    • Converting from the ’Shared SSL’ to a ‘Dedicated SSL’ such as a Godaddy SSL but not updating URLs

    • Navigation bar links

    • Any link referencing our deprecated shared SSL such as:



  • How do I know if my links are old? Examples include referencing outdated ‘Shared SSL’ URLs::






    • Or older.

  • I’m still using your ‘shared SSL’ what is the correct format?

  • I have alot of links, how can I find them? Using a free tool such as will allow you to see how fast,slow, large files, or slow files affect the load time on your site. Corecommerce has already put in place many optimizations to decrease load times. Poor judgement and implementation of third party code / incorrect links however will cause delays.
