Hello!
The service "fpcentral" (https://fpcentral.tbb.torproject.org/) will be retired on October 20th 2021 (6 months from now), along with the server it is running on (forrestii).
We do not have the resources to maintain the service. Besides, other, and better alternatives have emerged since then, like, for example the EFF's Cover Your Tracks service (https://coveryourtracks.eff.org/, previously known as the Panopticlick) and TorZillaPrint (https://arkenfox.github.io/TZP/).
On the retirement date, the server will be shutdown, rendering the service completely unavailable. A week later, the server will be destroyed, and its backups will be destroyed 30 days after the retirement date. The Internet Archive has an up to date copy of the site's static assets and will be able to keep it for posterity. It is recommended that you fix any bookmarks, links, or other references you have to this site.
If you have concerns about the retirement or wish to delay the procedure, you can add a comment to the tracking issue (https://gitlab.torproject.org/tpo/tpa/team/-/issues/40009) or contact TPA:
