Perhaps no one knows.... The browser object has a flag to indicate whether you're online or offline. It could be that - it cannot detect whether you're online without testing it. Does your firewall indicate where the attempted connection was being made to?
i just captured two IPs now.
IP: 18.104.22.168 (Google Inc.)
IP: 22.214.171.124 (PTCL) (PTCL is my ISP)
first thing came to my mind that it's pinging, second thing it's resolving dns, but it's not icmp or dns port. it's port 80 which is web port.
may be C2 games has google analytics in it? or something like that?
i don't have any browser object in my game, actually it's a first tutorial by C2, i just tested it by exporting it, and it contact internet.
it would be good if C2 team can throw some light on it.
