please solve missing 200px size of an picture, see https://upload.wikimedia.org/wikipedia/commons/thumb/5/57/Status_iucn3.1_LC_cs.svg/200px-Status_iucn3.1_LC_cs.svg.png Other sizes works correctly, see https://upload.wikimedia.org/wikipedia/commons/thumb/5/57/Status_iucn3.1_LC_cs.svg/201px-Status_iucn3.1_LC_cs.svg.png for example.
This image is very frequented in the articles. I triaged this as unbreak now and put a notice at #wikimedia-tech therefore.
I get ERR_CONTENT_DECODING_FAILED as the error code (Chromium). Lastly when I saw this kind of error it was because the server was lying about used compression. It seems to be a problem of only one/several clusters as not all users get the error (@elukey can't reproduce it but @ema who is according to information at IRC close to me and probably using same cluster can).
See https://cs.wikipedia.org/w/index.php?title=Wikipedie:Pod_l%C3%ADpou_(technika)&oldid=14873106#Dal.C5.A1.C3.AD_problematick.C3.BD_obr.C3.A1zek for information what it shows now (just a place for the image+alt).
- Chromium 56.0.2924.76
- Firefox 52.0.1
Other tried ways how to access an URL
- wget 1.18 (no problem)
- curl 7.50.1 (no problem)
- curl 7.50.1 with spoofed user-agent (no problem)
Seems it affect only users not bots.
