Why domains lapse, and what it costs to get one back.

The renewal notice went somewhere nobody reads

Registrars do send warnings. The problem is where they go. Domains are frequently registered by whoever was around at the time, using their own email, sometimes a personal one, occasionally an address at the very domain that is about to expire. When that person leaves, the notices continue arriving somewhere that no longer matters.

The second common cause is a card. Auto-renew is switched on, everyone relaxes, and three years later the card has been reissued and the charge silently fails. The registrar emails about it, to the same address as before.

What happens on the day

The moment a domain expires, the registry stops publishing its records. Not gradually and not with a warning page. Lookups fail, so the website becomes unreachable and mail delivery stops at the same time, because both depend on the same records.

Confusingly, the registrar control panel may still show the domain as active, because renewal is technically still possible. To everyone else on the internet it is already gone.

The thirty days that follow

Most registrars offer a grace period during which the previous owner can renew at the normal price. The length varies a great deal by registrar, from around a month at some to almost nothing at others, so the assumption that there is always a comfortable window is a bad one.

After the grace period comes a redemption phase, where recovery is usually still possible but at a substantially higher fee, often in the low hundreds. After that the domain is released and can be registered by anyone.

Where it stops being a money problem

Expired domains with any history are watched by people who register them automatically the moment they become available. If that happens, you are no longer negotiating with a registrar. You are negotiating with an owner, if they respond at all, and the price is whatever they decide it is.

Businesses that have operated at the same address for a decade sometimes find there is no route back. Every printed card, every vehicle, every link from a supplier, every email address for every member of staff, all pointing at something you no longer control.

What actually prevents it

• Register the domain to a business address that survives an individual leaving, not a personal one
• Add a second contact address so a single unread inbox is not the only line of defence
• Turn on registrar lock so nobody can transfer it away without anyone noticing
• Check the card on file has not expired, which is the failure people are most surprised by
• Know the renewal date somewhere other than in the registrar's email

That last one is the whole point. The renewal date should exist somewhere you will see it even if the notice goes astray, which is what a standing record is for.

A note on who this catches

It is tempting to think this happens to disorganised businesses. In practice it happens most often to organised ones with turnover of staff, because the process that worked depended on a person rather than a system, and the person moved on. The domain kept renewing without anyone noticing until the day it did not.

The pattern underneath all of this is examined in nobody owns your domain.
