I’m experimenting with where I want to host tech blogs, but I put this short one on Write Freely

tl;dr - my S3 storage costs were at $26/month more than I expected due to Longhorn (storage volume management for kubernetes) making over 5M s3_list_objects calls. Turning off that polling should fix it.

edit - the polling flag didn’t fix it. I updated the blog with a new approach from a github issue that blocks network access outside of backup hours.
