Cheatsheets not being served via nginx #44087
Description
We started synchronizing the cheat sheets from this repo, to the pandas.pydata.org server. The cheatsheets have been correctly placed into our website directory, but https://pandas.pydata.org/Pandas_Cheat_Sheet.pdf is still serving the old version.
I restarted nginx, to make sure it's not a caching problem, but still the same. I deleted the file, and still being served. I checked the nginx logs, and all requests are being logged, except to the cheat sheet files. I checked the nginx configuration, to make sure there is nothing specific to that file, and it's not. I uploaded a different pdf to the same directory, and worked correctly. I stopped nginx for couple of seconds, and the website was down, but the cheat sheet was still being served.
The only thing I guess it may be causing this, is a cache in a service like cloudflare or similar. Do you know if we're using that @TomAugspurger @aterrel ? And do you know if the cache will be purged anytime soon? Happy to wait until the cache is automatically purged if it'll happen, but would be good to understand if that's the case.
