RE: YouTube cache node 50.151.220.26 not accepting TCP from my area (YouTube buffering)

Same cluster, same problem here (Broward County, FL). It's not just .26. 50.151.220.21, .24 and .26 all ignore TCP 443 from my connection. Ping to them works fine at ~12 ms, the SYN just never gets answered.

It breaks Play Store downloads too, not only YouTube. Android resolves rr9.sn-bvvbaxivnuxqjvhj5nu-hp56.gvt1.com to .24 and hangs on it for 130 seconds every time. Updates sit on Pending, then fail.
