Patrick, my name is Hari and I'm with AppDynamics Support. Firstly, apologies for the service interruption on this environment. Notes from our internal operations team suggests that this service incident was resolved around 7:47AM (or thereabouts) Pacific time today (9/27/2016). You should have access to this Controller now. Kindly confirm.
Re: your question about a status page, we do not have a robust 'real-time' status page on a per user basis. But you should be receiving a notification about Service Interruptions via an email based notification mechanism we have in place. Do you not have any emails this morning from no-reply@portal.appdynamics.com around this incident timeframe?
