There's a new page accessible by clicking "Recently-deleted pages" in the top-right dropdown of any page:
That page serves as a little "trashcan" for your pages when you delete them. Any page that you've deleted in the past 24 hours will show up there, and you'll be able to restore that page (un-delete it) from there. After 24 hours, your page will be permanently deleted (as it is now), but now there's a place to go to if you ever accidentally delete a page. :)
In other news, the site infrastructure has been running super-smoothly for the past week, and I have been continuing to work on optimizing the back-end to make it faster and faster. Happy to report even temporary downtime seems to be a thing of the past now; we're running on awesomely-huge servers with plenty of room for growth now. :)
