Email sign-up form not loading

We encourage people to sign up for our email lists two ways:

We have a hyperlink on our webpage that goes to the really long url for the sign-up form and we have a bitly link. When either one is used, it is currently common (and has been for several days) for the page to "time out" and not load. I just tried with from both sources and could only get the sign-up form to load when I refreshed the page. I assume this is a problem at your end.
