Retool affected by Cloudflare outage?

Hi there :wave:

Between 12:00 and 13:00 CET we were unable to access Retool due to CORS issues. The screen stayed blank and the browser console showed CORS errors on several JS and CSS files.

There was a short Cloudflare outage during the same timeframe. Could this outage have been the cause of the issue?

I believe it’s the same incident, none of our apps are loading during the Cloudflare outage.

However it would be great if the Retool Status page reflected the issue to confirm.

Attempting to access any of the URLs on https://retool-edge.com leads to the same error as other properties affected by the Cloudflare outage.
