| As part of routine updates, we went through each of our machines and ran regular system updates. | ||
|
|
||
| Two of the updated packages included `libicu` and `libvips`. The affected machines involved were the `mastodon-web` machines, known as `fritz` and `buttons`, and `mastodon-sidekiq` machines, known as `franz` and `freud`. `nietzsche` is our database server, which we are in the process of replacing. |
