Also I plan to do the pictrs update this weekend (the one I said I'd do over easter but didn't, mostly because I spent my time playing DREDGE 😆). I don't know how much down time there will be, in my test run the site seemed to stay up while it migrated. Hopefully this is the case here!
I'll also start trimming the cache as well. Currently lemmy saves full size images to display thumbnails, and never deletes them. So we have about 260GB of image data just sitting there. Someone built a tool to delete the cached images after a set amount of time, and I've been testing it out. There were some teething issues but everything is working nicely now so I plan to add this as well. This is mostly to help the backup process, which fails the offsite transfer part semi-regularly because of the size (and some weird speed issue we can't get to the bottom of).
So I'll do these two things possibly starting tonight for the pictrs update then do the thumbnail cleaner once the update is done, possibly tomorrow some time, taking advantage of lower traffic over the weekend.
Also the lemmy.world saga is definitely not over. They have implemented a new system that can reject kbin traffic if they start seeing huge volumes again, but currently we are back to having a lot to catch up on:
With our special setup we are getting posts and comments straight away but the votes are delayed by about 1.5 days at the moment, which means Hot and Scaled will not really show lemmy.world posts because they will have 0 votes unless it has been a couple of days, and Hot ranks posts with a time decay which means the lemmy.world stuff won't make it up to the top.
