How often do supply drops drop?
In The Division as of the 1.1 "Incursions" update we receive supply drops within the DZ.
How often do these supply drops happen within a 24 hour period? Or is it completely random?
Ubisoft official release notes only say:
Supply drops will occur multiple times over the course the day
However, according to the numerous sources1 2 3 the drops are hourly, though I'm not sure if that actually means exactly once every 60 minutes. Playing for about 2h in DZ I've seen two supply drops.
Update: It seems to be at different times for different DZ servers. I managed to see 3 different drops in span of just half an hour on 3 different DZ servers (you get switched when joining friends on other servers).
