Firebase storage Quota has been exceeded

Sorry you had issues! Here are some answers:

• Was it the billing account? Or that was a random incident?

Unsure why it happened--it's possible that there's a bug in our quota system, or it's possible that you ended up storing or sending more data than you thought. I'm not sure how you're using storage, but if you've got a 400kB image and we have a 1GB/day limit, that's 2500 downloads/day. If you've got 200 users, and they use the app routinely, and the file is downloaded on app start every time, that might explain extra usage.

Our free plan offers 30GB outgoing bandwidth per month, 5GB of data storage total , and 20,000 uploads and 50,000 downloads operations per day--once these limits are hit, the app won't work until the quota resets, or until you upgrade your app. Once you upgrade, the quota limit is removed and the app works, which is why your problem went away.

• How often the limits reset?

The bandwidth is 30GB/month, enforced as a daily limit (so every 24 hour period means you're allotted 1GB of bandwidth). This limit resets every day.

Storage is 5GB total, and once exceeded you need to remove additional data (or upgrade your plan) before the app works again.

Operations are 50,000 downloads and 20,000 uploads per day.

See the quota limit docs for more info.

• Where can I see the actual limits for each service/feature?

We're working on exposing usage data for each service in their respective sections of the Firebase Console. Stay tuned for more on this.

I had te same issue, I had upgraded it to blaze plan and then deleted some of the data from the storage and then again downgrade the plan to free and it will start working for testing
