DRUPAL MAINTENANCE FREQUENCY
We recommend that every customer has a maintenance contract in place. However, there’s a big difference between, say, a brochure type of website (which may need to maintain a few times a year) and an eCommerce site (which will need maintenance weekly).
Below is the breakdown of our recommended website maintenance frequency. Disclaimer: If there is a security update, then you should update your site right away, no matter your maintenance plan.
