Control messages

Which control messages this endpoint answered, per draft. An error reply is still an answer — ok and err are both support; what is recorded as missing is a message that got no answer at all. A dash is neither: it means the exchange ended on our side, so nothing about this endpoint was measured there.

Notes

  • — the peer is up but refused the offered protocols on at least one transport

Is this your relay?

If something here is wrong, tell us — we keep what each result rests on, so a disputed one gets re-read rather than re-argued. We can also run this against endpoints that are not public.
