like tens of thousands. some children are like that. so, we take this as an opportunity to learn a bit more about knot tuning we shortened `tcp-idle-timeout: 2` we set `tcp-max-clients: 20` rate limiting seems unlikely to improve things as it is many sources, a DDos what else are we missing? btw, it also whacked knot enough that it failed a resign cycle and we had to add `unsafe-operation: no-check-keyset` to get back to signing. clues appreciated. this can't be the only neighborhood with children. randy --
