Our yacy search engine is back online and fully operational. And it is now upgraded to the most recent release. Upgrading provided a substantial improvement in crawl rate but at the expense of higher memory consumption. All in all though the performance increase
was worthwhile.

For those who are not aware, yacy is a federated search engine. When you put in a query,
it queries all the federated servers (there are some stand alone and isolated yacy networks), and collates and returns a combined result.
