I tried several deploys, via github, manually and manually with clean build cache. In all cases, the build is reported as successful. However, the content doesn’t show up properly.
HTTP header last-modified says 8 Jan, whereas content on that page was definitely edited in the past few minutes (on 9 Jan).
Trying the same URL but adding a random querystring param (cache buster) shows the right content. This says that the cache is at fault here.
How can we manually or programmatically clear the cache?
