Hi @futureweb,
Boulder doesn’t consume the PSL directly, instead we use the publicsuffix-go library which itself updates the PSL via frequent auto-pulls. Given that, I think your question is best expressed “What is Boulder’s publicsuffix-go update schedule?”.
Right now the answer is that we do it on an adhoc-basis. I will typically cut a pull request to update the dependency if someone asks 
The last time I did so was 16 days ago - perhaps that included the domains you’re interested in? I can verify if you’re willing to provide a list.
(Note: as always there is delay between when something is merged to master and when it appears in staging & production. You should follow https://letsencrypt.status.io/ for deploy status & changelogs).
Thanks!
