Hi,
Because of schema changes happening in production, the s1/enwiki wiki
replica is currently behind by ~40 hours, so tools and bots relying on
it will have outdated data.
The expectation is that it should recover by Monday. You can look up the
current replag using <https://replag.toolforge.org/> and discussion
about the issue itself is at <https://phabricator.wikimedia.org/T310325>.
