We want to enable[[ https://www.mediawiki.org/wiki/InstantCommons | InstantCommons ]] on cloud but are not sure how much traffic this will result in for real commons. We want to make sure we're being good internet citizens.
Questions we want answered:
* Does it cache:
* The actual image files on the server?
* Check this by turning on InstantCommons locally + adding loads of files + using the browser network tools to see if they come directly from commons or if they come from the local wiki.
* Metadata i.e. the links to those files?
* check this by looking in the cache and seeing whether stuff is cached.
If so:
* where are the cashed files stored?
* will we get rate limited?
* this is hard to be certain about but maybe try adding loads (50+) of files and see what happens locally
