As someone from Europe: This looks exactly like the 15h UTC peak in most US websites and chats when all the Americans come on.

The peak starts at 12h UTC, is largest at 18h UTC, and goes down at midnight UTC – exactly what I’m used from US people in the chats I am,

and exactly 4am PST, 10am PST, and 4pm PST.

or 8am Eastern Time, 4pm Eastern Time, and 10pm Eastern Time.

Which is Silicon Valley Morning/Workday, East Coast Workday, and European Evening.

Same as reddit.
