Database access problems on site

[MandyShaw]

Yesterday and today I have experienced database access error messages:

Sorry! This site is experiencing technical difficulties.
Try waiting a few minutes and reloading.

(Cannot access the database)

Backtrace:

#0 /home/cpdlorg/public_html/wiki/includes/libs/rdbms/loadbalancer/LoadBalancer.php(972): Wikimedia\Rdbms\LoadBalancer->reportConnectionError() [etc.]

This happens in many areas of the site, and both on Chrome and on Edge, and both when logged out and when logged in. Refreshing the page usually, but not always, fixes the problem.

I can't see that this has been reported here previously.
Is this a known issue that's being looked at?

Thanks

Hi Mandy, we are experiencing some issues with robots that crawl the whole website at a very high speed, causing a very high server load. We are trying to apply countermeasures, however the situation is still a little bit critical.

Thanks Max, hope the bots lose interest in CPDL soon!
