Monday was December 25th, Christmas Day. All non-essential services and offices were closed in most of the Schengen zone. Many workers take leave a few days before Christmas and between Christmas and New Year, so even if offices are "open" they might be operating at a reduced capacity.
Visa will still be processed, but I'm not surprised if the decision takes a few days longer. (That goes for positive and negative answers.)
