Slate enforces rate limits on form submissions to reduce spam and maintain the stability and security of your database. To do this, Slate tracks the IP address from which each form is submitted.
Most users never encounter a rate limit because they access Slate from a variety of IP addresses, such as home or cellular networks. In rare cases, though, a large group of users may share a single external IP address—for example, when attendees complete a form during an on-campus presentation. The rapid volume of submissions from one network can trigger rate limits and block legitimate responses.
To prevent this, configure Slate to apply a higher rate limit for specific IP addresses or ranges.
⚠️ Caution!You should only authorize IP addresses or ranges to have an elevated rate limit if you can largely trust the users on that network (e.g., your campus network.) Elevated rate limits on too many IP addresses or ranges risks increasing spam submissions.
Adding IP Addresses to allow Elevated Form Submission Rate Limits
Navigate to Database and search for Configuration Keys
Under Security & SSO Settings, open Subnets: Increase Form Submission Rate Limit.
In the corresponding pop-up, enter a comma separate list of IP addresses. You may also use CIDR notation to specify a range of addresses.
Save.
Configuration Keys are cached on our web servers and refreshed approximately every 15 minutes. After the cache has refreshed, you will see the elevated rate limits take effect for form submission from the selected IP addresses.
