I'm going to be making some changes on infosec.exchange and associated instances to move the object storage off our self-hosted minio server and onto Hetzner's object storage service to reduce costs in line with donations. This may cause some periodic intermittent issues with media uploads since it's (probably) not going to be as fast or reliable, but I'll work to mitigate that as best I can. Hopefully I can make this change without anyone noticing, but if you see issues over the next week or so, that's likely the cause.
