Your account was blocked because build exceeded allowed resource quotas number of times. Unfortunately we cannot say what specific quota was hit in this case (issue on our side).
We unblocked your account. Please cancel queued builds and restart them (or only those which you consider important).
Next time you see build error with this message, please ping us and we will elaborate on what quota was exceeded and help you to avoid this. Account will not be blocked after first error like this, only after certain number.
