## Run down

The same procedure as every year: This platform update will affect all Apps (Uni and Pro). The expected downtime for App web delivery is up to 20 minutes, we aim for a few minutes. We will run the updates sequentially, App after App. For the deployment services (Git, SSH and SFTP) we expect a maximum downtime of around 30 minutes. Please keep an eye on our [status page](https://status.fortrabbit.com) where we are going to post intermediate updates.

## A note on PHP 7.4 (and PHP 8.0) EOL <span id="php-74-eol"></span>

So far, we have been able to keep the unsupported versions PHP 7.4 and PHP 8.0 running well after their sell-by-date. There will be no updates, patches and security fixes from the PHP maintainers any more. Thus, these two PHP versions are provided from us at best effort. If a serious security issues comes to light, we will need to force update to the next PHP version with short notice.

Please review your Apps with us, see what still runs on PHP 7.4 or PHP 8.0 and you are able upgrade.

We know that it is painful and we feel you. We don't wan't to break your websites. We understand that there is often no time or budget to keep all projects updated. Yet, it is your duty as the maintaining developer to keep your software updated.
