Hi,
it seems that since some hours, the analytics s1 slave (s1-analytics-slave.eqiad.wmnet, db1047.eqiad.wmnet) database cannot by reached at all via mysql.
This affects all services using enwiki (like geowiki), but also all services relying on EventLogging.
I filed RT ticket #7385: https://rt.wikimedia.org/Ticket/Display.html?id=7385
Best regards, Christian
P.S.: Sean indicated [1] that there are problems around db1047 and masters, so it might be a related, temporary issue. But Icinga shows also non-db related critical errors.
