The update code back up and running … it was off for a while - can’t recall exactly, maybe November to late December?
When I turned things back on I noticed that my OSM data server (I self-host an Overpass API server) was broken. That’s why some cities got updated but didn’t include recent OSM changes. That’s fixed now, though.
It appears to be going through 50-100 cities per hour. I think it can go faster - it’s mainly held up by the reprocessing that has to occur after cities are updated.
I’m not certain if the “zero nodes” issue is resolved.
