In a recent mail the Parse team mentioned January 28th 2017 is when Parse APIs would stop responding.
If your app uses Parse, the best immediate course of action is to host a private instance of the Parse Open Source Server on a Cloud Instance (or Dedicated Instance if you choose). Migrate the data to the new server.
There are simple ways to ensure there is no downtime during this activity. You could follow the migration guide here. I am available on a pro bono basis to help with the migrations.
