I saw this and it bothered me. I found I had the same problem, perplexing. Now I have a solution. Check your logs (see vidalia "advanced" tab). Look for time errors. Looks like tor doesn't handle DST changes well.
I restarted tor, and now I can connect to this, and some other sites that I was having issues with. Oh, before you restart, check your system time!
Is anyone still having connection issues? Traffic to the site died off by about 30% a couple of days ago, couldn't figure out why. Did daylight savings time mess up tor?
I showed it to a friend and we browsed around a bit. Though, I checked again now, and now I am getting errors. The vidalia logs show:
[Notice] Closing stream for '[scrubbed].onion': hidden service is unavailable (try again later).
On the other hand, even over the past few days, I had no problem on some onions. I was testing coin tumbler a few days ago and it just stopped (I can see the transactions in the block chain, its just sitting there so frustratingly!). However, I haven't had any connection issues, and I have been watching the site obsessively since it has some of my coins

So I don't know what to tell you about connection issues. I am curious though, I may turn up debug logging and see if anything comes up. I really want to see hidden services take off
