The site is absolutely fine but there is only so much capacity on the web server. Between say 6pm and 10pm UK time the server starts to fall over because users on both sides of the atlantic are using the site at the same time. This spike in numbers causes problems as there is only a finite amount of connections the system has available. So at this time just be patient and wait a few minutes. Trying to log on repeatedly when the site isn't working will make the situation worse, and prolong the error messages whilst the server is trying to reset itself. On another note, sometimes the server works for some and not for others. This is due to locations of server, the locations of users, the ISP you are using and the server nodes bouncing your request to the web server and back. Unfortunately there's nothing site users can do about this. It's just the nature of the internet. I hope this helps explain some of the problems you might be experiencing.
