The big test will be when we hit peak load, perhaps on Monday or Tuesday.
It's a bit disconcerting how often I say "close to a decade now" now.
* Edit: we do rate-limit some accounts (https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que...), which throttles how much they can post to the site, but we don't throttle how quickly they can view the site.
Ever since I read someone's comment that 'HN is the fastest site they regularly visit', I've wondered if that's because they're in the western US (where HN is hosted).
I am in Western Europe and HN is decently fast, but tweakers.net and openstreetmap.org are faster.
