I am definitely seeing multiple requests coming in at the exact same time.

This seems to be because the request timed out. I'm seeing a request taking over 48 seconds and nginx returns an error 499. I'll bet that this causes the button to re-enable and the user clicks again at that point.

We need to fix our slow queries.

EDIT: Validated that when this happens the user actually gets an error screen. They can then click back and go back to the request page and do everything again since at that point the request hasn't been fulfilled yet. That seems to be what happened.

I'm wondering if this has something to do with vacuuming - maybe it happens to be going on at that exact moment.

Noting that during the planning meeting we determined that vacuuming wasn't happening at the time of the issue.
