thx! it looks interesting. Since I wsa using a custom ring middleware, maybe there were some headers missing or something (although I find it super weird that changing the query string did not reloaded the css, nvm any http header!). Also weird that it got "fixed" on its own. Will take a closer look at the article
@emmanueloga Caching issues are known to be unstable and hard to reason about, so I feel your pain.
