If a lot of people access SR through onion.to (which I believe is the case), then it would already have an established circuit to SR and wouldn't need to fetch the descriptor. Anyway, I'm getting this error: onion.to silkroadvb5piz3r.onion is currently unavailable. Proxy timed out while trying to connect. (4). You might have been able to access it through an existing circuit that has been severed now. Try again.
