In DNS records, the A record for @ (your domain itself, such as yourdomain.com) shows a lock, and you cannot
change, delete or duplicate it. This is deliberate.
The reason: automatic failover
Our hosting runs in two data centres, in Maryland and in Buffalo, which keep copies of your sites and mailboxes. A monitoring service watches them around the clock. If the active data centre has a problem, it changes the address your domain points to, within a minute or two, to the other one. That only works if this address is the one we set.
If the record pointed elsewhere, or a second A record for @ existed, part or all of your visitors would end up at the
wrong place during a failover, or your site would be unreachable.
What you can change
Everything else: www and other names, mail (MX), TXT records for SPF, DKIM, DMARC and verification codes, and so on.
See Manage your DNS records.
For other names that should reach your website on our servers, add a CNAME to your domain; it follows the failover automatically.
If you need the domain itself to point elsewhere
For example when your website moves to another provider while your email stays with us: contact us. Our staff can change the record for you, and we will tell you what that means for the failover.
