Just wanted to let you know: At least for me the official playground on https://play.crystal-lang.org/ isn’t working/ even opening.
The page (seemingly) loads forever (on Safari - if relevant) and the console contains an error:
Error: Ember Data Request GET /languages returned a 502
Looks like a problem with https://carc.in/ and I don’t think we control that
Sorry, my monitoring let me down, should be back up 
@jhass I’m currently in the midst of building an alerting/monitoring SaaS. Let me know if it’d be useful for this or other core Crystal dev stuff, nightly builds, etc.
Thank you, the problem was more one of too many messages already, I just wasn’t attentive enough
