What are the limitations to submissions to a form

[ChristopherKreuter]

I am building a application form that is predicted to get 20,000 submission in 48 hours. Does anyone know if this will cause issues?

@ChristopherKreuter   If your survey does not have photos and you are using ArcGIS Online, 20K records within 48 hours is not out of the ordinary. 

If your survey allows respondents to send photos, audio or file attachments, please contact your Esri account manager or send an email to survey123@esri.com referencing this Esri community thread so we can discuss in more detail the specifics.
