［小白求助］突然不能访问 facebook 和 google， ping 和 traceroute 都不行，但能访问 instagram 和 pinterest

同一账号在同一网络环境下在其他设备上能正常访问，自己本机莫名奇妙访问不了，之前都好好的。急死了，向大神们求助

本机：mac yosimite10.10.5

香港阿里云应该是已经科学上网，能访问 instagram

PING instagram.com (52.54.154.226): 56 data bytes 64 bytes from 52.54.154.226: icmp_seq=0 ttl=233 time=436.585 ms 64 bytes from 52.54.154.226: icmp_seq=1 ttl=233 time=271.024 ms 64 bytes from 52.54.154.226: icmp_seq=2 ttl=233 time=375.758 ms 64 bytes from 52.54.154.226: icmp_seq=3 ttl=233 time=262.759 ms 64 bytes from 52.54.154.226: icmp_seq=4 ttl=233 time=255.305 ms 64 bytes from 52.54.154.226: icmp_seq=5 ttl=233 time=560.771 ms

但 Facebook 和 google 打不开网页

PING facebook.com (157.240.15.35): 56 data bytes Request timeout for icmp_seq 0 Request timeout for icmp_seq 1 Request timeout for icmp_seq 2 Request timeout for icmp_seq 3 Request timeout for icmp_seq 4 Request timeout for icmp_seq 5

traceroute 的结果：
