okay. so then there’s something wrong with your ISP’s connection to the AWS image set specifically then. it’s possible they’ve purposely throttled it. maybe they have limited shared bandwidth and think that activity associated the image host is consuming a disproportionate share of the traffic, or maybe it looks otherwise suspicious? or maybe they just have a bad connection to the AWS server? in any of the cases, it’s probably best to call your ISP to resolve whatever the problem is.
tell them you’re having trouble loading images from iNat’s AWS image set. for example: https://inaturalist-open-data.s3.amazonaws.com/photos/232635346/medium.jpg.
