Memorandum of Understanding

Hosting a RIPE Atlas Anchor

Version 5.1, Updated 28 March 2019

Hosting the RIPE Atlas Anchor using either the Hardware Anchor or Virtual Machine (VM) Anchor, (either of them referred to individually as the “Anchor” and collectively as the “Anchors”) contributes to the expansion of the RIPE Atlas Internet measurement network and enables the Anchor Host to benefit from additional benefits of the RIPE Atlas service that are exclusive to Anchor Hosts.

By accepting this MoU, the RIPE NCC: Agrees to provide data collection back-end services and data presentation services as described in the public documentation regarding the RIPE Atlas service, available at:

Agrees to provide best efforts to keep the RIPE Atlas network up and running for at least the duration of the service provided to the Anchors. Whereby the duration of the service to the Hardware Anchor is set as the duration of the hardware service contract with the reseller or manufacturer and the duration of the service to the VM Anchor is set for a period of three years from the moment it becomes publicly available as a measurement target in the RIPE Atlas network.

Agrees to provide best efforts to deliver value-added services for the Anchor Host in addition to standard RIPE Atlas services. That includes more measurement credits and possibly other additional services.

Agrees to provide the target functionality for Anchors, including offering the Anchor as a possible target to RIPE Atlas users.

Agrees to publicly list the Anchor and provide other visualisations, anchoring measurements towards the Anchor as a target, and possibly other additional services.

Agrees if applicable to arrange delivery of the Hardware Anchor to the Anchor Host in cases where the Anchor Host obtains their Hardware Anchor from the RIPE NCC directly. The Hardware Anchor will remain the property of the RIPE NCC.

By accepting this MoU, the Anchor Host:

Agrees to adhere to the RIPE Atlas Service Terms and Conditions.

Agrees if applicable to purchase the Hardware Anchor as specified by the RIPE NCC – unless the Hardware Anchor is provided by the RIPE NCC.

Agrees to install the Anchor as per the requirements provided by the RIPE NCC so it can function as an Anchor in the RIPE Atlas network.

Agrees if applicable to maintain the hardware, if purchased by the RIPE NCC, in good condition and return it to the RIPE NCC if the RIPE NCC decides to replace the hardware with different hardware, or if the Anchor Host decides not to use the hardware as a RIPE Atlas anchor.

Agrees to provide proper Internet connectivity, rack space and power supply for the Anchor in order to make it reachable as a target, and in order to make it usable as a RIPE Atlas anchor.

Agrees to communicate with the RIPE NCC about any change in their connection status as an Anchor Host, and about any plans for discontinuing using the Anchor.

Agrees, to the best of their ability, to keep the Anchor connected and operational at all times, and provide their best effort to solve problems in case of issues with the hosted Anchor.

Agrees to be responsive to specific emails/requests made by the RIPE NCC. If the Anchor Host is unresponsive for three months, the RIPE NCC may terminate this MoU. Anchor Hosts are considered to be unresponsive if they do not react to a specific email/request made by the RIPE NCC, regardless of whether the Anchor is still connected and operational. Does not count the RIPE NCC liable for any damage that might be caused by hosting the Anchor.

Honours the right of the RIPE NCC to choose who can or cannot host Anchors, and who can or cannot have access to the RIPE Atlas service at any given time.
