I have the good fortune to live in Fla and can watch the launches from the backyard. I was disappointed that there is a two minute delay on space.com and I almost missed the amazing launch tonight! Can anybody explain the delay?
Occasionally, those feeds from SpaceX and NASA can have delays in their broadcast that stem from their delivery online. You can notice it when comparing, for example, a SpaceX webcast and NASA webcast for a Dragon cargo mission. Or between NASA's Livestream and YouTube channels.
Space.com actually does not intentionally add any delays into livestreams, as they are provided directly by the broadcaster.
I hope this helps, and am glad you were able to see the flight.
