Cron jobs can be configured to run at different times (minutes, hours, days, months or at any other combination of these).
On the shared servers however (end user and reseller hosting plans), we allow them to run at 15 minutes intervals, because excessive cron jobs can overload the server and cause instability for the hosted websites.
If you need them to run at less than 15 minutes intervals, we recommend you to take into consideration upgrading to VPS hosting plans.
Note! Our servers have monitoring systems meant to detect the cron jobs configured at less than 15 minutes intervals and as they will be identified, they will automatically be changed to run at 17 minutes intervals.
