Continually degrading response

Brian M
Over the last few days access to multiple wiki's (very noticeable on
enwiki) has been getting increasingly worse.  Is there a back-end issue
going on?

Best regards,

Can you elaborate?

My first response to a question like that is to check graphs.

e.g.
* https://graphite.wikimedia.org/render/?title=navigationStart%20to%20loadEventEnd%20on%20desktop%20sites,%20last%20month&vtitle=milliseconds&from=-1month&width=1024&height=500&until=now&areaMode=none&hideLegend=false&lineWidth=1&lineMode=connected&target=alias(color(frontend.navtiming.totalPageLoadTime.desktop.overall.median,%22blue%22),%22Median%22)&target=alias(color(frontend.navtiming.totalPageLoadTime.desktop.overall.75percentile,%22red%22),%2275th%20percentile%22)

* https://graphite.wikimedia.org/render/?title=mediaWikiLoadStart%20to%20document.onload%20on%20desktop%20sites,%20last%20month&vtitle=milliseconds&from=-1month&width=1024&height=500&until=now&areaMode=none&hideLegend=false&lineWidth=1&lineMode=connected&target=alias(color(frontend.navtiming.mediaWikiLoadComplete.desktop.overall.median,%22blue%22),%22Median%22)&target=alias(color(frontend.navtiming.mediaWikiLoadComplete.desktop.overall.75percentile,%22red%22),%2275th%20percentile%22)

from https://gdash.wikimedia.org/dashboards/frontend/

that looks fine to me.

Another graph to check is currently broken:
