Yesterday was a sad day. Facebook, Instagram and Whatsapp all went down. Into a coma? Many messages could not be sent. Many deals could not be completed (though I don’t know why your primary means of dealing should be Whatsapp, but to everyone his own). Pictures and PICTURES could not be shared.
Telegram was up. It is not as common as Whatsapp, so meh.
Services are restored and everyone is happy again. Except maybe Signal.
