Topic on Talk:Page Previews/Flow

Hi,

I'm not sure where Page Previews pull their content from - I've found one this morning that differs wildly from the article it links. On the 2017 Honduras General Election page (link A, below), under the Supranational bodies header, when you hover over "Organization of American States", the preview text reads:

The Organization of American States, or the OAS or OEA, is a continental organization that serves to control American puppet states in the Americas. Headquartered in the United States capital Washington, D.C., the OAS's members are the 35 independent states of the Americas.

This is not an objective or factual statement, and differs wildly from the article that the OAS link leads to. The word "puppet" appears nowhere in the article source - which was where I went first in my attempt to find and revert the vandalism.

The previews feature is great, but I really hope that it is refined so that vandalism is easier to revert/address in the future.

The article was vandalized 23:21, 1 June 2019. The vandalism was fixed within one minute.

For some reason the vandalized version remained as the active version in the page-preview cache for over 17 hours. I preformed a purge on the affected page which successfully cleared out the vandalism.

I'm not an expert on the caching, but one of the devs might want to look into why a few seconds of vandalism got stuck in the cache for so long. Is it possible the two edits were asynchronously processed in the wrong order? It would be bad if the software didn't spot something like that. A swift revert like this tends to be a significant red flag for blatant vandalism.

P.S. 143.85.163.1 thanks for the report. Any edit to Organization of American States would have fixed it. It can also be fixed by purging the page, adding ?action=purge at the end of the OAS address and loading it. Like this: https://en.wikipedia.org/wiki/Organization_of_American_States?action=purge

This problem still exists. The preview for Angolan Civil War is vandalized, but I cannot find the text anywhere in the article. It's really aggravating.

This is currently a problem on [[wikipedia:Gateway Arch]]. Vandalism was rolled back within a minute, but the irrelevant first image is still showing up in the page preview. I wasn't sure how/where to report this? (sorry, unsure of how to link to a particular page from in here)
