If this gets blocked, Deezer regularly pops up a faulty error message, to say it can’t  access the internet, while all normal functionality is in working order.

I believe it relates to some of the tracking Deezer has implemented. While tracking is normally bad, I do understand Deezer needs some form of tracking to better provide recommendations. In light of this, can we get a bit more clarity on what exactly is being tracked by services using this hostname? Even better would be a list of Deezer’s background services and their related endpoints.
