Hello Stuart,

Do both server clusters serve the same data via the API and are they updated simultaneously?
all overpass-api servers try to keep in sync from osm.org data via minute "diff" update. but from time to time, that fail or take a little more time. every group of server have often their own sysadmin, it's not a group that takes care of all the overpass-api servers. modern overpass api version return the info with a line like this : <meta osm_base="2020-02-10T13:42:02Z"/>
