Hello:

There are replication issues regarding Eventlogging data. 

For some tables (see: https://wikitech.wikimedia.org/wiki/Incident_documentation/20151022-EventLogging) data has not been replicated since 2015-10-22.

All dashboards read from the slave rather than master so the data they display is outdated until this issue is resolved. Ditto for any query running on 1002. 

You can follow the work of our DBA on this regard on the following ticket:

Thanks, 

Nuria
