Is Ancestry.com's "Lübeck, Germany, Citizenship Register, 1591-1919" Working?

The database "Lübeck, Germany, Citizenship Register, 1591-1919" at Ancestry.com appears to not be working. When searching it for the last day or so, I get "this page is temporarily unavailable."

Admittedly I was searching for Flessner which is not the most common name. 

However, there should be a few names in this database matching a last name search of Sch*

Even that search gave the same error message.
