Root Cause Analysis:  As part of our release process, when a site is migrated to a new deployment, the site’s custom CSS needs to be processed (compiled and minified).  The service/application responsible for this is called mindtouch-node-services. Changes to our "built-in" CSS caused the mindtouch-node-services application to take longer than 30 seconds to minify the CSS.

Recovery:  At approximately 20230217 4:45 UTC, the `clean-css` upgrade was deployed and everything was back to normal. 

Corrective Actions 

1. CXone Expert has upgraded to `css-clean` 
2. CXone Expert is currently working on code changes that can give us a better understanding of the bottlenecks that affect this service. 
3. CXone Expert is upgrading our version of nodejs to provide better performance. 
4. CXone Expert is testing a nodejs process manager that can spawn multiple nodejs processes to prevent slowness when the nodejs event loop is blocked and cannot take on any more work.  This will require some performance tests to be written and executed.
