The outage was due to a change that one of our Service Providers (AWS) released to our infrastructure.
We have now worked around this unplanned change. The API is now getting back to a normal state, but it will take a few minutes before the service is fully up again.
We are ensuring that further changes to our infrastructure by our providers won't affect the reliability of our API.
Thank you again for your patience and I felt the 'dev' love for our pain
