Was working but getting internal server error message now

Please fix it. Ive had good functionality until now and now its giving an internal server error and the customer service number it prompts to call is disconnected when I call it. Having an app fail the day you fly is a problem. I can still check info through the mobile aa.com website but thats not as easy to navigate as the app.
