They do, in fact, have a single satellite link to the world. They also have a single fibre link that terminates in Dandong.
Total bandwidth: 2500 Mbps.
Most DDOS attacks HERE easily exceed 3000 Mbps.
lol A lab at most colleges could kill their links, but their firewalls/routers would kill the IP communications. Would need to be done from multiple sites, unless they are idiots, running primitive gear. lol
