Real-time metrics show the loss of connectivity on leading network YemenNet (AS30873) on early Friday morning. It is not known if telecommunication infrastructure was specifically targeted, although visual investigations suggest this may be the case. The resulting information blackout is likely to limit coverage of events on the ground.
Visual reports appeared to corroborate initial reports of a strike. Al Hudaydah is the main landing point for internet connectivity in Yemen, hosting the undersea FALCON and SEA-ME-WE 5 cables that route via the Red Sea.
