alt Hacker NewsTried throwing a batch of known-to-be-in-Amazon ISBN's through (from a recent "export my data", so even if they're old amazon fundamentally knows them.) Got 500's for a handful of the first hundred, then a bunch of 502/503s (so, single threaded, but part of the HN hug to death, sorry!)
(Only the first 4 or so were json errors, the rest were html-from-nginx, if that matters.)
No hug of death, the server is sitting at 3% CPU usage under current load; it seems someone found a bug that triggered a panic, and systemd failed to restart the service because the PID file wasn't removed. Fixed now, should be back online :)
