Event quota Exceeded


I got this message:

Your organization has exceeded its event quota

As you can see here, I had a-lot of event from an update in which an error triggered many times. Later I fixed that error, but probably it was too late and Sentry got to many request from my free account.

My Question:
What does this graph accutally mean? Do I still produce so many errors. Or what’s the interpretation for the grayed-out bars?

When will my beloved sentry work again?
