January 2020 Monthly accounts data missing from the site

The monthly and archived accounts files seems to be missing January 2020

or

http://download.companieshouse.gov.uk/en_monthlyaccountsdata.html

There is no Accounts_Monthly_Data-January2020.zip file on any of these locations. Could someone please advise if there is something special about this month or if it really is missing?
