With so many visitors, we're reaching the request cap that Blizzard had given to us so we had to disable live guild requests in order to have the main page working properly. We hope that this will be resolved soon and we can have live guild updates up and running. We apologize for this inconvenience.
I have a suggestion on how to lower traffic for Live guild requests. For the moment allow only registered users to do live guild requests.
That way most people who are just 'gee wiz' curious where they stand will simply shrug and say oh well and people like me who like to track their guild's progression easily and efficiently will be able to via your awesome site :-D
