The main relay on the moqtail.dev fleet, and the endpoint the MOQtail project points at first.
The project owner states that MOQtail is not a production relay. That is worth reading before treating anything measured here as a service level — it is a demo fleet, and the TestLab sweep is a snapshot of one occasion rather than a claim about availability.
Elsewhere running MOQtail
9 other endpoints run the same implementation. Each is a separate deployment at its own version and configuration, so what one answers is not a claim about the others. All of them are run by the same operator as this one.
MOQtail ABR
MOQtailord.abr.moqtail.dev:443
The hostname did not resolve when the fleet was last swept — a fact about the name, not about any relay behind it.

Is this your endpoint?
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.
