I have problem with updating the whole guild. Whenever I try to do that I get the message "Armory is unavailable at the moment. Please try again later.", but the armory works very well. I can see my guild in the armory and also my character can be updated live.
Since WotLK came, we had to re-create the database, which means no characters were cached, and we had to take fresh data for each and every one of them from Armory. In the last few days over 500.000 characters were cached, which at the end caused a temporary ban from Armory (it lasts for 12 hours). We have several backup servers which work fine at the moment, but we only use them for single character view, because, if we make them available for guild updates too, they will probably also get banned fast. All this should be fixed very soon, since we wont have to pull so many records in the next couple of days. Thanks for your patience
