With only five data points so far this month for Chedita, it's a bit hard to say. That's probably what's causing the odd-looking state periods.
Looks like an expansion by the system controller from 13th-20th of September, which allowing for the lack of data doesn't seem that unusual.
Either the expansion failed (no targets in range) or it wasn't from Chedita, though, as there doesn't seem to be any sign of an expansion tax being paid. Looks like they have plenty of targets from Chedita, so maybe not expanding from there: looking at their other systems, expansion from Mictlan seems to have been more likely - not obvious to me where it went, presumably somewhere that doesn't get frequent updates to 3rd-party tools.
