#### Additional details

| Plan | Using SSL/TLS recommender? | Grace period ends |

- **Scan frequency**: Automatic scans currently occur approximately once per month, though they may happen more frequently in some cases (for example, configuration changes or upgrades). Scans stop when:

- The site is already using the most secure mode (for example, **Full (strict)**), or
- You switch from auto mode to **Custom SSL/TLS**.

- **Error checking before upgrades**: To prevent disruptions, Cloudflare checks for `5XX` errors (like `502` or `503`) and evaluates whether the HTTP and HTTPS content is consistent before upgrading a zone's encryption mode.

- **Upgrade notifications**: Cloudflare sends weekly digest emails listing which zones have been upgraded. These emails are currently sent to Super Admins only.

#### Opt out single zone
