Hello, I have a hobby plan
and this is my ussage. As u can see it is far away from exceeding any of the limitations. But now I am running a high budget add for 5 days from today so I don't know if that will exceed the limit. So I was concern what happens if my limit exceeds. Will I get a time period like 7 days or 30 days to upgrade plan or optimize my site? or the system will go down all on a sudden? Please acknowledge me about this. Thank You
Hi, ! Welcome to the Vercel Community 
When you exceed the limit, your deployment will be paused.
It's a good time to optimise now! Happy to help with that if you have any specific questions.
As the Hobby plan is a free tier there are no billing cycles. In most cases, if you exceed your usage limits on the Hobby plan, you will have to wait until 30 days have passed before you can use the feature again.
