This page contains information about the witnesses operated by the TrustFabric team at Google. This is the same team which developed and maintains Google CT logs, Trillian, Tessera, and TesseraCT.
The witnesses listed below conform to the C2SP tlog-witness@v0.1.0 and related specs.
Dev witnesses
These witnesses are intended for testing and development purposes only, you are welcome to integrate with them but they should not be relied upon for any reason. They are operated on a best-effort basis, and, while we do not envisage it happening regularly, they may be unavailable, withdrawn, reset, or have their keys rotated at any time and without prior notice.
transparency.dev/DEV:witness-little-garden

How to request witnessing of a log
Requesting via the Public Witness Network configs stored in the https://github.com/transparency-dev/witness-network repo is preferred, and is likely to be the fastest route to being provisioned.
Direct requests may also be sent directly to the TrustFabric team via issues on the https://github.com/transparency-dev/witness repo, or getting in touch with the team via slack.
