Yeah, your blog is inaccessible. Both on iCloud Private Relay and bare IP, Safari and Brave.
If my blog got DoS'd from HN was remotely close to any of these, would be perfectly normal but as it stands this is exactly why gatekeepers are perhaps inevitable, but should never be reveled.
If this amount of traffic across a small handful of users was enough to trigger a DoS, we should be getting proof-of-work captchas, not “you have been blocked” pages.
Perhaps there's an unreasonable geoblock configured.
