app was working on my own domain and then stopped

[Patrick Gray]

I have my own domain that I am trying to get my appengine app to work on and it started working last night and now it is no longer available.  The site on appspot is working but not on my own URL even though it is the same version.  on www.myurl.com it is giving me a message:

Oops! Google Chrome could not find www.url.com

Anyone know what could have started causing this or what I can do to fix it?
