Hi Benoit, Can`t say for sure how srf do it but in most cases this is done based on internet registry queries (RIPE db for example). Maybe you checked this already but it is possible that the specific IPs having the issue are not directly related to the /19 you mentionned but to a smaller more specific subnet which is assigned to a different country (or was recently as most of these applications do not make real time queries and only synchronise from time to time). Could you possibly provide one or two of the impacted IPs to see if they are part of the /19 or a smaller subnet?
In addition to this I also read that some content providers perform more checks on top of the IP layer, for example related to browser or media application settings, at this level only srf can give you more details. Anyway in my experience similar problems were almost always related to the subnet information in the internet registry...
