TrveKvlt... you have to keep trying. There is some intermittent thing in the DNS resolution. I do not think the site is up and down -- I think it's just up -- but I have noticed that if you type in bitbook.biz, it only comes up nine times out of ten.

You simply have to keep on trying. Once you get it, hold it for a while.

Things to try

1) incognito mode
2) http://bitbook.biz
3) www.bitbook.biz (both work)
4) firefox
5) (sigh) internet explorer

There is some kind of jogging of browser cache going on here. Please keep trying and let us know.
