# New Certificate Authority for custom hostnames

The following changes in CAA used to issue certificates for all Umbraco Cloud sites' for new and existing custom hostnames.

{% hint style="info" %}
**Not sure if your Cloud project is using a CAA record or not?**

You can use this [CAA Test](https://caatest.co.uk/) to check whether a CAA record is configured on your hostname(s).
{% endhint %}

## Certificates for new custom hostnames

Starting September 26, 2022, certificates are issued by **Google Trust Services** instead of **DigiCert**. The validity period of certificates has been reduced from one year to 90 days.

## Certificates for existing custom hostnames

From October 31, 2022, certificate renewals will no longer use 'DigiCert' as the issuing CA. The renewed certificate will instead be issued by 'Google Trust Services', and certificate validity will be decreased from 1 year to 90 days.

No action is required unless you set a Certificate Authority Authorization (CAA) record on your domain.

From October 31, 2022, Certificate renewals will no longer use 'DigiCert' as the issuing CA. This means that you need to update your CAA record to allow 'Google Trust Services' issuing certificates for your domain.

The CAA record should be changed from:

```sql
example.com. IN CAA 0 issue "digicert.com"
```

to

```sql
example.com. IN CAA 0 issue "pki.goog"
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.umbraco.com/umbraco-cloud/go-live/manage-hostnames/ca-record-migration.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
