I think our use of Hydra is not sustainable. It requires regular manual intervention by Mark, careful tuning of SQL queries, conscientious clean up of old substitutes, and we have not a single person familiar with the Perl code. We do have people working on Cuirass, though. Let=E2=80=99s add important missing features to Cuirass instead of making efforts to keep Hydra on life support. > It would be really great to get another pair of machines with similar > capabilities. I agree. We need volunteers to pick a particular configuration (my suggestion is to start with an Overdrive 3000 rack server[1]) and find a place to host these servers. We have not been successful in delegating this to other people and unfortunately the maintainers cannot take care of this themselves. [1]: https://shop.softiron.com/product/overdrive-3000/ -- Ricardo
