Looking at WDQS lag <https://grafana.wikimedia.org/d/000000489/wikidata-query-service?panelId=8&fullscreen&orgId=1&refresh=1m&from=now-10d&to=now> and [[ URL | Wikidata lag ]] in parallel, I don't see a clear correlation between the 2. There have been a few data reloads last week (you can see the spike on lag on the WDQS side), but the servers should be depooled during that operation. And the spike on lag is only 2h. It looks like the Wikidata lag is always at 43.80 weeks. This looks like a NaN converted to something wrong, or an overflow of some kind. @Addshore: you might have a better idea of what's could be happening on the Wikidata side. Side note: exposing both the MySQL replication lag and the WDQS replication lag through the same value seems like a bit of an abuse of the system. Would it be better to expose both separately and let the clients have a more specific interpretation of those numbers?
