!! ADMIN POST !!
seems like we haven't had images load for a bit over a week; apologies for taking so long to address this. the cause was that the SSL cert for the object storage domain (files schelling.pt) had expired, as I had forgotten to renew it at the same time as the primary cert for the root domain. I've resolved the issue & will try to find time to automate the cert renewal so that we don't face this issue again
major thanks to @WomanCorn and @TetraspaceGrouping for pointing this out!
a Schelling point for those who seek one

Only just got here, but reflexive updoot for transparency from admin
