(I'm Doug, not Jim) I don't know what you mean guys, what you're referring to when you say click on the site. I mean you're both posting messages here so if you're getting an error how can you be posting messages ?
Sometimes I really despair at the level of knowledge about the Internet and simple ability to actually read. Doug, he's not saying CoinTalk is down, he's saying that Error-ref is down. And it is. Most hosting plans have a limit on how much traffic you can receive or send per month. Once you reach that limit, you get an error page back - which is what Error-ref is showing. Since those pages are static, it's possible you would see it from your browser's cache - try to jump to a page you haven't visited recently.
It's considered a little more professional to track bandwidth yourself and have the web host (Apache here) throw up a low-bandwidth intercept page just before the hosting company shuts you down. You are supposed to remember to create a custom error page for 509, but people rarely remember to do it (in fact I don't remember seeing it on any of the "12 steps to setting up your Apache web site lists"). With most hosting plans, there's a lot of traffic in your allowance, so you just don't expect to exceed your traffic limits. Of course you can't always control if/when you get slashdotted/reddited... (that's where somebody posts on ./ or reddit "hey found this really cool site" and 2 million new users click on the link - you can get several months worth of traffic in an hour that way) But using the bandwidth limit in Apache means that (maybe) you limp until the next month at least telling people something is up, vs. looking like you skipped town and stole all the bitcoins... oh wait, that's the crypto-currency exchange exit strategy game.
