At 1:00 in the morning local time. When everyone (or almost everyone) would have been asleep.
No fire suppression system. No fire alert system. Residents told to shelter in place until the fire department rescues them. One stairwell in the center of the building.

From the vids I’ve seen on UK news sites of how quickly it went up, that building may as well have been built from wicker and painted with tar.
