Been exploring how each directory authority measures relays and noticed that, over the week of May 24–30, Moria1 consistently reports significantly fewer relays measured than its peers—about 6% missing versus ~3.5% for most other authorities (over 2 σ below the mean).

Quick stats (May 24–30):

Attached the full spreadsheet, some tables, and charts below.

Has anyone else spotted this pattern or have ideas why Moria1’s “number of relays voted about” is lower? Any insights or pointers would be greatly appreciated!
