I’m getting a 500 when visiting fly.io (I’m in the UK):
When I run flyctl status or any flyctl commands, I get:
Error server returned a non-200 status code: 503
Same here from India.
I have information from fly support that there was a downtime of the API.
We still can’t access it completely, but seeing some recovery. Might take some time. 
This should be mostly resolved, we’re monitoring the situation.
ssh commands just started hanging for me, and my colleague just got the 503 error when doing flyctl ssh issue: Error server returned a non-200 status code: 503
I’m currently getting a different error when running running flyctl ssh console: Error can't establish agent: Post "https://api.fly.io/graphql": unexpected EOF
Updated again the status page, looks like the fix was wrong.
This is now resolved. There was a pretty nasty issue with our database (still hosted on RDS, moving it to ourselves in on our todo list).
