EDIT: Looks like it has been updated now (6:49 PM UTC)
"Firebase Data Connect unavailable due to a known Google Cloud global outage"
While the Google Cloud status page https://status.cloud.google.com/ says "No major incidents" and everything is green. So Google Cloud know there is an outage but just deem it not major enough to show it.
Edit to add: within 10 minutes of this post Google updated their status page. More curiously the Firebase page I linked to has been edited to remove mention of Google Cloud in the status and now says "Firebase Data Connect is currently experiencing a service disruption. Please check back for status. ".
Meanwhile anyone using an intersection of TypeScript with jest and any of sindresorhus' libraries when he flipped to ESM for his bajillion libraries immediately felt the downside and moved hard away from ESM.
Imagine the mind-boggling hours lost just to get these export/import formats to glue.
