Seems that it is currently working. I haven't been able to test end to end but the sandbox seems to be up so that's promising. 

Sadly, no.

Didn't know that existed, and I do have access it seems.Besides a demo environment (UI) it doesn't seem to be useful in terms of API access. Or I can't seem to find a way to enable it.Thanks for the suggestion though.

I'm looking to perform an end-to-end test towards a Cisco Meraki integration. Since these sandboxes aren't working. Can anyone let me know how to achieve this?
