Hello, The reason they are there is to document their existence in case someone wants/needs to know. They also exist in the API. However, you're right stating these are no longer active. We'll clarify this in the documentation. Thank you, Robert On Sat, Nov 1, 2025 at 4:12 PM Ernst J. Oud <ernstoud@gmail.com> wrote:

Hi,

An addendum for the RIPE team.

The documentation at: https://atlas.ripe.net/docs/getting-started/built-in-measurements mentions the following builtin measurements:

1030 <https://atlas.ripe.net/measurements/1030> ctr-ams02.atlas.ripe.net 1031 <https://atlas.ripe.net/measurements/1031> ctr-ams03.atlas.ripe.net 1029 <https://atlas.ripe.net/measurements/1029> ctr-ewr01.atlas.ripe.net 1028 <https://atlas.ripe.net/measurements/1028> ctr-fnc01.atlas.ripe.net 1017 <https://atlas.ripe.net/measurements/1017> ctr-nue13.atlas.ripe.net 1019 <https://atlas.ripe.net/measurements/1019> ctr-nue17.atlas.ripe.net 1027 <https://atlas.ripe.net/measurements/1027> ctr-sin02.atlas.ripe.net

However these are obsolete since a year. The documentation should reflect this.
