With the recent upgrade frenzy, leading to 2.8.0.beta2, something strange happened that I’m currently investigating. The effect is that on a multi-site install, _some but not all_ secondary sites do not respond anymore. The primary site is up, and some secondary sites operate normally.

~~I suspect it may have to do with the [discourse-calendar](https://meta.discourse.org/t/discourse-calendar/97376/234) issue already reported on stable, but that’s just a hunch.~~
