My personal favorite is the website for reporting large international transactions, which can only be using during regular working hours on weekdays.
What exactly is that? Is it for moving savings from a non-eu country into Germany ?
How they describe it: https://www.bundesbank.de/en/service/reporting-systems/exter...
Any single transaction exceeding 12500€ entering (or leaving) Germany has to be manually reported here. So for example if you're living in Germany and working remotely as a contractor for a US based company you'll probably have to report your income every month.
There are many exceptions that don't need manual reporting though, like if you're buying physical goods from overseas. I guess those are already automatically tracked through other ways.
For fun, I just tried to login at ~9:30 PM local time on a Sunday, and it said:
"Access Denied"
"You cannot access the resource you have requested at this time."
"The resource you have requested is protected by a policy restricting access to specific time periods. Your request has occured outside of those permitted time periods."
