Here are some points to note before you submit a quota increase request:

It usually takes up to 2-3 weeks to review and make a decision regarding your quota increase request. Do not reach out to us for an update.
The decision (rejected/accepted) will not be communicated to the site owner. If there is no noticeable increase in quota on Google Cloud Console within 3 weeks, it is safe to assume that your request was rejected. Note: The most common reason for a rejection is when a request fails to meet the annotation requirements, or when it does not belong to the live broadcast or jobs category.
If you assess that your site fits the live broadcast or jobs category but you didn’t get a quota increase, we encourage you to review your page annotations and if necessary resubmit your request.
Do not reach out to Google for the status, ETA or the reason why quota was rejected.

Moving forward, Google reserves the right to either increase or decrease your quota. Requesters may have questions about these changes. Due to proprietary reasons, we can’t give you a specific reason as to why the quota for your site was changed. We can, however, tell you that any additional change in quota will be influenced by the overall utility of the URLs submitted.
