We apologize for the disruption, but https://kf.kobotoolbox.org/ is currently down due to an issue with our hosting provider, Amazon Web Services. This issue appears to be isolated to the US region where the non-humanitarian server runs and is not affecting the EU region where https://kobo.humanitarianresponse.info/ is hosted.
As of 13:00 UTC, Amazon has released this statement:
We can confirm a loss of power within a single data center within a single Availability Zone (USE1-AZ4) in the US-EAST-1 Region. This is affecting availability and connectivity to EC2 instances that are part of the affected data center within the affected Availability Zone.
We will continue working to restore service as quickly as possible. Thank you, as always, for your patience!
