It seems like the dark (tangent-like) line running through the middle of the uptimes (not the conspicuous vertical stripe you describe) is just a consequence of the sorting.
Yes, how it works is we first sort by center of mass, then by total uptime. The center of mass moves from left to right as you look from top to bottom.
It turns out that there are many descriptors that are only up for one or two hours out of an entire month. Those are what make the dark stripe.
The big surprise is how many descriptors there are. In November, there were 13,242 unique descriptors seen, more than double the steady-state total number of relays. Many relays appear for a short time and then disappear forever. The black band at the center consists of the actual stable relays. Above and below that is a lot of churn.
Are the vertical white lines periods where a consensus wasn’t reached?
Yes, there are some missing hours in the input files.
