CXServer is alerting in production with:
/v1/page/{language}/{title}{/revision} (Fetch enwiki Oxygen page) timed out before a response was received; /v2/page/{sourcelanguage}/{targetlanguage}/{title}{/revision} (Fetch enwiki Oxygen page) timed out before a response was receivedThe reason for it is that, due to the work being done in T220461: Simplify storage semantics we are not storing old revisions any more. Consequently, it takes longer for RESTBase to respond to requests for older revisions. CXServer uses old revisions of large pages in its tests, causing the automated checks to time out. In order to mitigate that, we can use the latest revisions of lighter pages.
