Netlify function crash with 2 000 simultaneous connexions

Hi, we encounter a problem with the website id 63c3e255-73fa-4361-91f5-65c9d0960b83

This morning, We encounter a netlify crash between 10:55 am and 11:10 am.
Netlify relaunch automatically and after that our website run fine.

This morning at 11:00am, we had 2000 simultaneous connexions (different users) and we think that is the cause of the problem.

We expect to have more than 10000 simultaneous connexions this week-end, can you help us identify the problem ?

Thank you by advance.

Could you provide more details about the crash? What did you see? Did you get an error? If so, what was it?
