I'm consistently getting:
The page at https://en.wikipedia.org says:
Error loading data from server: parsoidserver-http-bad-status: 404. Would you like to retry?
Other articles seem unaffected.
Version: unspecified
Severity: normal
URL: http://titanium.wikimedia.org/enwiki/19th_Virginia_Infantry?oldid=561398978
I fixed the particular issue by asking for a purged version from the cache directly, but this might be a wider issue? oldid=561398978
So far this seems to be an isolated case, which would be compatible with us not properly distinguishing between API request errors and non-existing pages. A single API hickup would then lead to a cached 404. Needs investigation.
We've got a second case on https://en.wikipedia.org/w/index.php?title=Red_shiner&oldid=561424824

And a third case on http://en.wikipedia.org/w/index.php?title=National_Institute_of_Open_Schooling&oldid=563517112 (which I discovered in my volunteer mode)

I am not able to reproduce this after a cache purge. This means that these errors are definitely not systematic to some title or revision, which fits with the API error suspicion.
