I doubt that we saw "WolvesTV" in action for the Bremen match - that was most likely a hacked-together HTML5 player running off the same server as the main site, which is why it crashed when so many people were accessing it, rather than a dedicated streaming service with its own host. That said, that they're now specifically mentioning that they want people to watch the next two matches as a stress test makes me wonder if they now think they've underestimated how much bandwidth they'll need to be providing per match for the coming season.
