Hello
If it is any consolation....
I am a
fully paid up subscribing member of Ancestry.co.uk. Up until lunchtime today I could access everything on the site.
Since lunchtime, however, I cannot access very much at all. Even the 1881 census is not fully available

I am assuming that there must be some updating or maintenance taking place on the site that has caused a temporary problem for some subscribers and non subscribers alike.
With any luck it might be very short term

Optimistically
DS
