I can only speak for the Brax3 Version 7.3 looking to download.os-source.co . I am not sure where previous versions were/are currently looking… If I had to guess I would say ota.iode.tech … I will say this though… If/when Brax does fix the pointer to the correct hosting server(s), that/those server(s) are likely to become busy. So they are just probably trying to “prepare” for the data load (of which they haven’t had before) to insure it can’t disrupt whatever else the host servers might be doing. They also will probably want to capture a good bit of information on the first official hosted update, so as to fine tune how they choose to support update demands in the future.
