Since approximately mid-November on enwiki, Mapframe maps have not always been displaying markers when they should. See https://en.wikipedia.org/wiki/Module_talk:Mapframe#Maplink_markers_not_appearing_in_article_space for reports from users, but basically, for the same article they are only rendering some times or for some users. For example, they appeared when editing but not when saved, or appeared for some users but not others, or can be made to appear by saving an edit. Possibly they are only working when rendered by some servers but not others?

I also observe that lately it takes hours or days after page save until map content matching dynamic view becomes available on snapshot image. E.g. in this article map was added three days ago and on snapshot I currently still don't see OSM object that is auto-positioned in dynamic view. Or, in this article I observed the same yesterday, while now snapshot highlights the OSM object, but the object has become missing in dynamic view.
Could the issue be similar to T266807? Per Grafana 100% CPU usage remains to be more or less an issue, If I'm not mistaken. I suppose users seeing different output is due to different level of unstability in eqiad and codfw?
Thanks to @Evad37 for reporting. I just want to add that the marker/shape sometimes does show initially in article space, but subsequently it can disappear and then reappear. That's even after I link the Wikidata item to the OSM item and it does that initial cache which shows it. This article for instance I am sure showed it previously, but doesn't presently.
Thanks for your assistance.

I just tested every machine in production (after your comment) and it looks like maps1001.eqiad.wmnet is the one serving the same content cached for this URL, all other machines are serving a different output (the correct one)
