The site is used by my students at CCSU for our online magazine. Perhaps one of them hit the wrong key.
Do your students manage the site using your account? It might be a better idea to have your students create their own accounts, and then you add them to the site as authors or editors. That way they can manage content on the site, but they won't have the access needed to make changes to upgrades, the theme, or to delete the site itself.

I see the address: bluemusemag.com is back up and running. So his has been restored.
It hasn't been restored yet. I restored the cancelled upgrades, and that means the domain will work as it's still in a post-cancellation holding period. The moment it enters redemption it will stop working, though, so we need to hope it is restored before that happens.
Is is correct, that we will need to re-up our premium plan next month?
Your plan will expire on 4 February, as it has not been renewed yet, so you'll need to renew it manually, but please wait until after I've confirmed that the domain has been restored.
