A domain expiring takes the website and the email down at the same moment, and the first the business hears of it is a customer asking why the site is gone. The site shows a parking page, the mail bounces, and the renewal notice turns out to have gone to an address nobody reads anymore. Here is what is going on underneath, and the three settings that keep it from happening to you.
Why the site and the email go down together
Your domain is the name. The DNS records attached to it are what turn that name into a website address and a mail server. When the registration lapses, the name stops pointing at your nameservers, and every record you set stops being served at once. The website is unreachable even though the hosting is fine. Mail sent to you cannot find a server to deliver to; the sender’s system retries for a while, then bounces the message back to them. Nothing waits in a queue for the name to come back.
What the registrar does next
Registrars do not delete the name on the day it expires. First comes a grace period in which you can still renew, though the site may already be showing a parking page. After that comes a redemption period, where the name can still be recovered, for a fee on top of the renewal. Then the name is released, and anyone can register it, including people who resell names that still get traffic. Each stage costs more than the one before, and the clock started on the day of the lapse, whether or not anyone noticed.
How long each stage lasts and what it costs varies by registrar, which is a reason to know yours before it matters.
How it happens to sensible people
Nobody forgets a domain on purpose. It lapses because the renewal was on a card that has since expired, or the registrar account was opened years ago by a developer who has moved on, or the reminder emails go to an address from the old office. When a site comes into our care, the registrar login is the first account we ask about, because a business that does not hold it does not really hold the name.
Making it a non-event
Three settings. Auto-renew on, with a card that will still be valid next year. The registrar account in the business’s own name, with the developer as a contact at most. And renewal notices going to an address someone actually reads, and in a small business that is the owner’s.
When a site comes into managed hosting with us, those three things get checked alongside the DNS and email records, because none of the rest matters if the name goes away. And if you have never looked at what hangs off your name, the DNS records a small business actually needs is the short list.
