Delisting

You can ask us to stop showing your endpoint on this site. This page says what that achieves and what it does not, because the difference is real and a page that implied otherwise would be promising something we cannot deliver.

What we will do

• Stop rendering a record page for the endpoint.
• Remove it from the archive index, the agent-facing index and the sitemaps.
• Exclude it from any figure this site publishes from that point onward.

Write to [email protected] from an address at the domain in question.

What we cannot do, stated plainly

Delisting cannot un-publish history. It removes a server from this site going forward. It does not reach the snapshots already published, and it cannot, for a reason that is structural rather than a matter of willingness.

Each published snapshot commits to its records through a single root, published at the time it was made. Every record inside that snapshot contributes to that root. So an already-published observation of an endpoint remains committed to by a root that is already in public hands — removing the row now would change the root, and a root that changes is not a commitment. The archive can grow. It cannot retract.

Two further limits worth knowing, since they are the ones people are surprised by:

• We observe endpoints that are publicly listed elsewhere. Delisting here does not remove a server from any registry that lists it, and does not stop anyone else from observing it.
• Anyone who already holds a copy of a published snapshot keeps it. That is what makes the record checkable by someone who does not trust us, and the same property means we cannot take it back.

What we will not pretend

We are not going to write that we will delete all data about a server on request. It would read better and it would be false. The honest offer is the one above: we control what this site shows going forward, and we do not control what has already been published — including by us.

If the problem is that a specific observation is wrong rather than that you would prefer not to appear, corrections is the better route: a correction carried forward is more useful to you than a removal, because it leaves the record saying something accurate rather than saying nothing.
