search.disconnect.me via Tor = poor connection

https://search.disconnect.me/ *

Recently, accessing to search.disconnect.me take very long time than usual, or just disconnected(can't connect). Other websites are working fine.

It's useless to me. Anyone have the same issue?

strangely, when I tried non-Tor IP address to connect search.disconnect.me, it shows instantly. Maybe search.disconnect.me is filtering tor connection in any way, like limiting speed.
