We have [some](https://gitlab.torproject.org/tpo/network-health/analysis/-/issues/24#note_2783983) [indicators](https://lists.torproject.org/pipermail/tor-relays/2022-January/020184.html) about serious non-exit relay general overload going on. We "solved" the *exit* relay issues by just not using the DNS failure metric anymore (see: team#139 for some analysis of the problem). We might need to tune our metrics that get triggered by non-exits as well. We should probably use our network-health relays in testing and figuring out what is going on. /cc @dgoulet
