Is Rike AMI instance still running?

Went through link

https://github.com/arago/rike/blob/master/AMI_QUICKSTART.md 

Click on link  - rike AMI 4.1(https://aws.amazon.com/amis/rike-ami-4-1/) gives me 404 error,

Please let me know if any other setting are required to run the application through amazon.
