> Some internal changes ahead


## Run down

The updates will affect all Apps (Uni and Pro). The expected downtime for App web delivery is up to 30 minutes, we aim for a few minutes. We will run the updates sequentially, App after App. Pro Apps on production plans are planned to have near-to-zero downtime.

For the deployment services (Git, SSH and SFTP) we expect a maximum downtime of around 6 hours. Also the updates will run sequentially, so the individual per App down-time likely will be less.

Please keep an eye on our (new) [status page](https://status.fortrabbit.com) where we are going to post intermediate updates.

### libsodium

With the inclusion of sodium in core PHP 7.2 the name-spacing was dropped. In other words, the extension is not available any more, but included with the PHP core. We see that very few clients are using it. We will contact those affected individually. We keep the old extension for PHP 7.1, so for now, you can still switch back the PHP version in the Dashboard, or you can also use this polyfill: [https://github.com/mollie/polyfill-libsodium](https://github.com/mollie/polyfill-libsodium).
