Translation server is offline or translation is not available

I am using Lando to build fresh Drupal 8 installations all the time (download and install drupal, import config, etc.), but sometimes the process fails, with these error messages:

In install.core.inc line 2287:

Internet: The translation server is offline.

The installer requires to contact the translation server to download a translation file. Check your internet connection and verify that your website can reach the translation server at <a href="http://ftp.drupal.org">http://ftp.drupal.org</a>.

Or this one:

Translation: The <em class="placeholder">Danish</em> translation is not available.

The <em class="placeholder">Danish</em> translation file is not available at the translation server. <a href="/index.php">Choose a different language</a> or select English and translate your website later.

Sometimes I have to run the build process a few times, before the time out doesn't happen. I think it happens when curl doesn't get an answer within 30 seconds, in which case it times out.

Sometimes it only times out for individual projects, in which case the process is completed, but with missing translations for those specific projects.

I wonder if it would be worth considering to create a health check for the translation server performance, to check if there is an answer within 30 seconds. First, just to log it and see if there is a pattern, secondarily to add extra resources, or debug the underlying code, to reduce response time.
