This morning WhatsApp is down in much of Italy. Today 25 October 2022 WhatsApp stopped working around 09:00 in the morning and at the time of writing it does not seem to have resumed its proper functioning yet.
On Downdetector the reports spiked in the early morning, with several users exchanging messages on the appropriate page.
The green messaging service appears to be completely offline, with the impossibility of sending and receiving messages or configuring the browser version of Whatsapp via the menu of connected devices. The other Meta services (such as Facebook and Instagram) seem to work correctly.
There are still no official confirmations from WhatsApp, but it still seems that the problem has not only affected Italy and Europe but a large part of the world.
