What is going on?

Same question 790hours/100 when db created 5 hours ago

Same here. Went from “<1 hour” to “9700 hours”, with almost zero use.

Thanks for reporting this issue. We found the root cause. It will be fixed soon, and the numbers will become as they were.

Fix has been released today at 12:50 CET. It should be either already back to normal for your project (mine is OK already) or will be fixed soon, as value is lazily updated in the background.
