My WordPress blogs have hit the HN front page a coupla times.
I got about 6000 hits in an hour the first time and 10,000 the second time.
WP-SuperCache coped admirably in both cases. The mod_rewrite caching was enough to cope with HN. (I sent the developer, Donncha O Caoimh, £10 with gratitude!)
But what really made the server cry: being on HN led directly to being on Reddit, where the second popular post got 80,000 hits in a day. In this case I had to put WP SuperCache into direct-cache mode. Then it was fine.
