Looks like it's more than just their API, possibly. My site is down as is my ability to login to their system. :/
Sorry to hear that :( Our app is doing fine, possibly you are relying somehow on their API? In any case deploys are also down so not much to do about it.
Think this might also affect scheduled tasks? My service that's supposed to run every 10 minutes hasn't checked in for an hour.. and I can't log in.
Edit:
I can log in now and my scheduled task is running again.
