The thing is, in WordPress, it's not uncommon to end up with a public URL that takes a few seconds to generate if it uses a few plugins or multiple queries on a low-end server. This is really just demonstrating that apache/nginx fall over at some point (usually what goes away first is the MySQL connection).
