All three of our 16GB RAM Sphinxsearch servers, generously donated by an anon (from 2 years of $150x3 free credit), have run out of funding and expired. This means there is no search.
We are figuring out a solution, since we cannot apply existing server resources without affecting archival, and we don't have any more funds to procure new services or servers.

Longer announcement upcoming.
