Have you identified the cause?
- pg 13y agoStill investigating, but Nick just turned off the site for non logged-in users to take the load off the system while we try to figure out what's going on.
- zmitri 13y agoIf you don't mind me asking, what percentage of page views are non logged-in users?

- slg 13y agoIt is interesting that this is the exact opposite action Reddit takes when they are having server problems. I wonder what that says about each respective community.
- smackfu 13y agoFrom a technical side, it probably means that Reddit is showing static pages to visitors while HN is showing dynamic ones.
- AlisdairO 13y agoReddit's previously stated that non-logged-in users cause substantially lower resource consumption per user - I imagine that's a more likely explanation.
- oceanplexian 13y agoReddit uses an edge-cache for all logged-out content. They pass logged-in content. A cached HTTP document in something like Varnish should take virtually no resources whatsoever. HN is on Cloudflare but they might not be caching pages at the edge (they should).
- aidos 13y agoPresumably there's only so much caching you can do it this case - the points change on articles every second. Not like everyone has to see the most up to date content but it would be a trade off (that many wouldn't like)
