Our custom reports were working fine up to about 25 minutes ago, at which point all of the MP.api calls suddenly started failing due to the following error:

"...has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource."

(This is on a custom report page that is hosted by mixpanel and which is trying to access https://mixpanel.com/api/2.0/jql/ using MP.api)

Are other people seeing the same issue? I'm assuming that something got messed up on the mixpanel backend server, but I want to make sure.

The reports have just as suddenly started working again, so hopefully it was something that got fixed on the backend.

Hi @vyrin, thanks for brining this up and giving an update on it! I have checked into it and it looks like we did have some slight downtime on a query around 4:30 pm Pacific time, but this has been fixed since!
