In the meantime, I switched back to download-o-o, and for my surprise I still got timeouts. This time it was mirrorcache-br-2.opensuse.org, instead. But probably Zypper misreported cdn-o-o timing out when, in fact, it was something else - mirrorcache-br-2-o-o in this case.
Hmm, OK. I'm taking that back. Zypper were right before. Now I have switched my official openSUSE Tumbleweed repos to cdn-o-o, and it started getting timeouts for some packages in the OSS repo. I can remember at least kernel-default-6.4.4-1.1.x86_64 and libqt5-qtwebengine-5.15.14-1.6.x86_64 (both are beefier packages) were among those. Which means that it times out sometimes during repo metadata refresh and sometimes during package download. I see that here in Brazil [1]there are more than 4 POPs (points of presence), so that looks good, I'd supposed. And latency does look really good to me:
