@aaronpk by blocking Apple server, since media files need to be uploaded/downloaded to the Apple server.

@sirshannon ooh looks nice! Thanks for the link.

@nitinkhanna yeah. Charles Proxy: www.charlesproxy.com

@aaronpk I would guess they're looking at traffic patterns and just dropping packets that match what they think are files being sent. Similar to how mobile carriers attempt to enforce limits on supported video resolution for data streamed over HTTPS security.stackexchange.com/questions...

@sirshannon Charles? Some sort of packet sniffer?

@nitinkhanna @aaronpk Dart throw guess number 2: port 80 is allowed but not all of the iMessage ports? Maybe we should crank up Charles and test this...

@oyam @aaronpk Gogo recommends turning off iMessages in their guide, so I’d assume it has to do with that. It’s probably causing iMessages to fail completely and iMessages is falling back to SMS (unless you had that explicitly disabled?).

@aaronpk Is maybe iMessages falling back on SMS? If there is no support for MMS, images would be left behind, and only text making it through.

@aaronpk I don't think they're looking at the packet but maybe iMessage has a different endpoint to which images get uploaded and that's blocked? They could very well have taken Apple's approval and blessings to do this, since that's their business plan. // @sirshannon

@aaronpk I probably know even less :)

@aaronpk Message size?
