If your website is currently live on the web, and you are in the process of switching hosting providers, you will need to re-point your DNS A (or “@”) record to the new host.
This post provides the steps for doing so when your DNS control is not at your domain registrar. (If your DNS is controlled at your domain registrar, click here.)
First, you need to take note of all of your current DNS records. A great tool for doing this is The WordPress Website Owner’s Emergency Checklist.
Next, if your current hosting provider is not also your current domain registrar and you have hosted email services, you will want to look at this post on what to do with email when switching hosts.
Also, keep in mind that if you are moving your DNS back to your domain registrar or to another premium DNS service, you will need to update the nameservers to point back to the domain registrar or to the new premium DNS.
If at the end of this post you are still unsure how to edit DNS, or feel uncomfortable doing so, contact your DNS provider and they will walk you through their specific process.
If they won’t provide that basic level of service in a timely manner, you may want to think about transferring your domain to a provider that will.
Editing Current DNS A Record
When you are ready to edit your domain’s A record, do the following:
Log in to your current DNS provider and navigate to the DNS management for the domain you are going to edit.
In the DNS management section, you will need to point the A record (also denoted as “@”) to your Synthesis IP address, which can be found in your Synthesis customer portal.
Take a quick look to see if you have any www records. If you do, make sure they are pointed to your A record (which would mean simply having “@” listed for the record) or to your Synthesis IP address, as described in Step 2.
Understand that DNS propagation takes a time to complete across the web. Typically it completes in 1-2 hours, but sometimes it can take 24-48 hours.
What does this mean? During the propagation process, anyone who tries to access the domain will get either the old IP address (which will take them to the old site) or the new IP address (which will take them to the new site).
If you edit your site during this time period, it is imperative that you be sure you’re accessing the new site. Otherwise the edits will go on the old site and will, obviously, disappear once propagation has completed.
