Scheduling forms not working

For some reason our COVID vaccine scheduling forms were working fine on a desktop computer at the hospital but we sent the links out to schools and none of them can get it to submit, it gives an error or does nothing, now they're saying the message says something about too much traffic.

Please accept our sincere apologies for the inconvenience this may have caused. We have received an update from our backend team that the issue is should be fixed. Please check and let us know if you still experience any issue. We will be happy to take a look again. 

Thanks!
