Nope - we are TTN! (The community, the volunteers, the users and the stack provider and core TTi team suspport staff) Its ultimately owned and run by TTI but I suspect as they are promoting across other LoRaWAN service providers and private network users (as demonstrated with the Chirpstack integrations/interop support) they are trying to treat as a 3rd party service wrt TTN. Not official just my observation/suspicion.
And indeed PB then has its own status page - where this incident is called out! bookmark https://status.packetbroker.net/
